Memoria Descriptiva

1.1.1.

Objeto

La temperatura es una magnitud que se debe controlar con bastante frecuencia en los circuitos electrónicos, sobre todo cuando trabajamos con elementos de potencia que disipan calor, las temperaturas extremas pueden llegar ser muy destructivas. Con un control eficaz de temperatura, bien por una desconexión del circuito o por ventilación forzada, podemos evitar daños en el circuito, impidiendo que al final pueda terminar deteriorándose. También una de las ventajas del uso de un control de temperatura en un circuito de potencia con un apoyo de ventilación forzada, es que con esto se reduce considerablemente el tamaño de los elementos disipadores, con el consiguiente ahorro en el peso, tamaño y también repercutiendo en coste final del circuito. En circuitos con baterías también repercute en la duración de las mismas porque la ventilación solo se activa cuando es realmente necesaria ahorrando energía acumulada en las mismas. 1.1.2.

Antecedentes

En el proyecto anterior, nos dimos cuenta de que la temperatura es realmente importante a la hora de planificar un proyecto. Varios componentes se rompieron al pasar de determinada temperatura debido a una fuente de alimentación en mal estado, por ello hemos decido hacer un controlador de temperatura con su propia fuente de alimentación. 1.1.3.

Justificación

El circuito empieza por la alimentación de 12V CC y con el diodo D1, el D1 es una protección contra descuidos por inversión de polaridad. A continuación un regulador ajustable un LM317, que entrega como máximo unos 100mA, este circuito se ha fijado a una tensión de 8,2V por medio de un divisor de tensión compuesto por R1 y R2.esta tensión es la que alimenta el IC2 LM311 y le sirve como referencia fija de tensión por medio de las resistencias R4,R5. El sensor de temperatura es el transistor Q1 muy común un BD137. 1.1.4.

2.1 Manual técnico En caso de error causado por un mal funcionamiento del circuito esta son las tensiones que tendrá que otorgar el circuito: PUNTOS DE TEST TP1 TP2 TP3

TENSION MEDIDA MASA 10,88 10,88

2.3 Manual de usuario Este circuito impreso tiene que incorporarse con el circuito que se quiere proteger de la temperatura. El circuito tiene que alimentarse a través del conector correspondiente a 12 voltios. Dispone de un conector donde se conectará el ventilador el cual se accionará solo, cuando el sensor detecte un exceso de la temperatura. (Si el ventilador se acciona nada mas conectar el circuito, no se preocupe se apagará en seguida o tiene que regular el potenciómetro que regula la sensibilidad del sensor). Para regular la temperatura de accionamiento del ventilador tiene que girar la aguja del potenciómetro con un destornillador plano.

There are two limitations on the power handling ability of a transistor average junction temperature and secondary breakdown. Safe operating area curves indicate IC – VCE limits of the transistor that must be observed for reliable operation; e.g., the transistor must not be subjected to greater dissipation than the curves indicate. At high case temperatures, thermal limitations will reduce the power that can be handled to values less than the limitations imposed by secondary breakdown.

LM111/LM211/LM311 Voltage Comparator 1.0 General Description The LM111, LM211 and LM311 are voltage comparators that have input currents nearly a thousand times lower than devices like the LM106 or LM710. They are also designed to operate over a wider range of supply voltages: from standard ± 15V op amp supplies down to the single 5V supply used for IC logic. Their output is compatible with RTL, DTL and TTL as well as MOS circuits. Further, they can drive lamps or relays, switching voltages up to 50V at currents as high as 50 mA. Both the inputs and the outputs of the LM111, LM211 or the LM311 can be isolated from system ground, and the output can drive loads referred to ground, the positive supply or the negative supply. Offset balancing and strobe capability are provided and outputs can be wire OR’ed. Although slower than the LM106 and LM710 (200 ns response time vs 40 ns)

the devices are also much less prone to spurious oscillations. The LM111 has the same pin configuration as the LM106 and LM710. The LM211 is identical to the LM111, except that its performance is specified over a −25˚C to +85˚C temperature range instead of −55˚C to +125˚C. The LM311 has a temperature range of 0˚C to +70˚C.

Note 4: This rating applies for ± 15 supplies. The positive input voltage limit is 30V above the negative supply. The negative input voltage limit is equal to the negative supply voltage or 30V below the positive supply, whichever is less. Note 5: The maximum junction temperature of the LM111 is 150˚C, while that of the LM211 is 110˚C. For operating at elevated temperatures, devices in the H08 package must be derated based on a thermal resistance of 165˚C/W, junction to ambient, or 20˚C/W, junction to case. The thermal resistance of the dual-in-line package is 110˚C/W, junction to ambient. Note 6: These specifications apply for VS= ± 15V and Ground pin at ground, and −55˚C≤TA≤+125˚C, unless otherwise stated. With the LM211, however, all temperature specifications are limited to −25˚C≤TA≤+85˚C. The offset voltage, offset current and bias current specifications apply for any supply voltage from a single 5V supply up to ± 15V supplies. Note 7: The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a 1 mA load. Thus, these parameters define an error band and take into account the worst-case effects of voltage gain and RS. Note 8: The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive. Note 9: This specification gives the range of current which must be drawn from the strobe pin to ensure the output is properly disabled. Do not short the strobe pin to ground; it should be current driven at 3 to 5 mA. Note 10: Refer to RETS111X for the LM111H, LM111J and LM111J-8 military specifications.

lead between the resistors and the input pins can result in oscillations that are very hard to damp. Twisting these input leads tightly is the only (second best) alternative to placing resistors close to the comparator. 5. Since feedback to almost any pin of a comparator can result in oscillation, the printed-circuit layout should be engineered thoughtfully. Preferably there should be a groundplane under the LM111 circuitry, for example, one side of a double-layer circuit card. Ground foil (or, positive supply or negative supply foil) should extend between the output and the inputs, to act as a guard. The foil connections for the inputs should be as small and compact as possible, and should be essentially surrounded by ground foil on all sides, to guard against capacitive coupling from any high-level signals (such as the output). If pins 5 and 6 are not used, they should be shorted together. If they are connected to a trim-pot, the trim-pot should be located, at most, a few inches away from the LM111, and the 0.01 µF capacitor should be installed. If this capacitor cannot be used, a shielding printed-circuit foil may be advisable between pins 6 and 7. The power supply bypass capacitors should be located within a couple inches of the LM111. (Some other comparators require the power-supply bypass to be located immediately adjacent to the comparator.)

8.0 Application Hints 8.1 CIRCUIT TECHNIQUES FOR AVOIDING OSCILLATIONS IN COMPARATOR APPLICATIONS When a high-speed comparator such as the LM111 is used with fast input signals and low source impedances, the output response will normally be fast and stable, assuming that the power supplies have been bypassed (with 0.1 µF disc capacitors), and that the output signal is routed well away from the inputs (pins 2 and 3) and also away from pins 5 and 6. However, when the input signal is a voltage ramp or a slow sine wave, or if the signal source impedance is high (1 kΩ to 100 kΩ), the comparator may burst into oscillation near the crossing-point. This is due to the high gain and wide bandwidth of comparators like the LM111. To avoid oscillation or instability in such a usage, several precautions are recommended, as shown in Figure 1 below. 1. The trim pins (pins 5 and 6) act as unwanted auxiliary inputs. If these pins are not connected to a trim-pot, they should be shorted together. If they are connected to a trim-pot, a 0.01 µF capacitor C1 between pins 5 and 6 will minimize the susceptibility to AC coupling. A smaller capacitor is used if pin 5 is used for positive feedback as in Figure 1.

6. It is a standard procedure to use hysteresis (positive feedback) around a comparator, to prevent oscillation, and to avoid excessive noise on the output because the comparator is a good amplifier for its own noise. In the circuit of Figure 2, the feedback from the output to the positive input will cause about 3 mV of hysteresis. However, if RS is larger than 100Ω, such as 50 kΩ, it would not be reasonable to simply increase the value of the positive feedback resistor above 510 kΩ. The circuit of Figure 3 could be used, but it is rather awkward. See the notes in paragraph 7 below.

2. Certain sources will produce a cleaner comparator output waveform if a 100 pF to 1000 pF capacitor C2 is connected directly across the input pins. 3. When the signal source is applied through a resistive network, RS, it is usually advantageous to choose an RS' of substantially the same value, both for DC and for dynamic (AC) considerations. Carbon, tin-oxide, and metal-film resistors have all been used successfully in comparator input circuitry. Inductive wirewound resistors are not suitable. 4. When comparator circuits use input resistors (eg. summing resistors), their value and placement are particularly important. In all cases the body of the resistor should be close to the device or socket. In other words there should be very little lead length or printed-circuit foil run between comparator and resistor to radiate or pick up signals. The same applies to capacitors, pots, etc. For example, if RS=10 kΩ, as little as 5 inches of www.national.com

tive supply. This signal is centered around the nominal voltage at pin 5, so this feedback does not add to the VOS of the comparator. As much as 8 mV of VOS can be trimmed out, using the 5 kΩ pot and 3 kΩ resistor as shown.

(Continued)

7. When both inputs of the LM111 are connected to active signals, or if a high-impedance signal is driving the positive input of the LM111 so that positive feedback would be disruptive, the circuit of Figure 1 is ideal. The positive feedback is to pin 5 (one of the offset adjustment pins). It is sufficient to cause 1 to 2 mV hysteresis and sharp transitions with input triangle waves from a few Hz to hundreds of kHz. The positive-feedback signal across the 82Ω resistor swings 240 mV below the posi-

8. These application notes apply specifically to the LM111, LM211, LM311, and LF111 families of comparators, and are applicable to all high-speed comparators in general, (with the exception that not all comparators have trim pins).

Cláusulas de índole económica.

En estas cláusulas se suele determinar la forma de pago en las distintas fases del proyecto: Pagos valorados. Mensualmente se hará, entre la empresa proyectista y la contratista, una valoración del proyecto desarrollado, con arreglo a los precios establecidos y con los planos y referencias necesarias para su comprobación. La comprobación y aceptación deberán quedar determinadas en 15 días. Abonos de materiales. Cuando a juicio de la empresa contratista no exista peligro de hurto de los componentes adquiridos para el desarrollo del equipo electrónico, éstos se abonarán antes de la finalización del proyecto según establezcan las partes, no obstante la empresa contratista podrá exigir las garantías necesarias para evitar la salida o deterioro de los componentes abonados. Descuento por equipo defectuoso. La empresa contratista podrá proponer a la empresa proyectista la aceptación de estas taras con la rebaja económica que estime oportuna si se ha observado defectos de funcionamiento en el equipo electrónico diseñado con relación a lo exigido en el pliego de condiciones. Si no quedara satisfecho la empresa contratista con la rebaja quedará obligado al rediseño y construcción de toda la parte del equipo electrónico afectada por los efectos señalados. Revisión de costos. Se revisarán los costos siempre que resulten modificados las condiciones económicas de los costos de materiales en una diferencia superior al 5% al valor prefijado del precio estipulado en el presupuesto. Cuando la empresa contratista requiera la ampliación de alguna de las especificaciones o características del equipo electrónico se deberá realizar un estudio económico del sobreprecio a pagar por la empresa contratista. De no haber acuerdo, la empresa proyectista quedará relevada del compromiso de ejecución quedando obligada al empresa contratista al abono total de todos los costes de mano de obra, y similares desembolsados hasta el momento por la empresa proyectista. Abono de obras. Los pagos valorados se abonarán dentro del mes siguiente a la fecha de redacción. Cualquier retraso sobre estos plazos será indemnizado con el interés oficial para efectos comerciales fijado por el Banco de España. Liquidación definitiva. En el plazo máximo de un mes desde la recepción del equipo electrónico por parte de la empresa contratista ésta deberá realizar la liquidación definitiva. De existir fianza, éste se devolverá en el mes siguiente a la finalización del plazo de garantía estipulado de no haber reclamaciones de terceros por daños, etc. 4.5. Cláusulas de índole legal En estas cláusulas se delimitan las condiciones en las que ambas partes podrán rescindir el contrato de construcción del equipo electrónico objeto del proyecto. Modificaciones de obra. El diseño del equipo electrónico podrá ser cambiado total o parcialmente por la empresa contratista, no obstante si la empresa proyectista se considera perjudicada en sus intereses, solicitará la indemnización a que se considere acreedora, y cuya estimación someterán las partes a la decisión de la comisión arbitral. En los casos de suspensión no correrá el plazo. Derecho de rescisión. La empresa proyectista podrá rescindir el contrato en los siguientes casos:

19


1. Cuando las variaciones introducidas en el equipo electrónico aumenten o disminuyan el importe total de ésta de un 20%. 2. Cuando por razones ajenas a la empresa proyectista pase más de un años sin poder trabajar en el equipo electrónico. 3. Cuando se retrase más de seis meses el pago de alguno de los pagos valorados estipulados. Rescisión por incumplimiento del contrato. En el caso de retraso injustificado sobre los plazos fijados se impondrá a la empresa proyectista una multa de 1,5% del presupuesto asignado como pago valorado. Liquidación en caso de rescisión. Se hará una liquidación única que será la definitiva con arreglo a lo estipulado en este pliego. Cuestiones no previstas o reclamaciones. Todas las cuestiones que pudieran surgir sobre interpretación, perfeccionamiento y cumplimiento de las condiciones del contrato entre ambas partes serán resueltas por la comisión arbitral. La comisión arbitral deberá dictar resolución después de oídas las partes dentro de los quince días siguientes al planteamiento del asunto ante la misma. Durante este plazo, la empresa proyectista deberá acatar las órdenes de trabajo indicadas por la empresa contratista sin perjuicio de proclamar las indemnizaciones correspondientes si la resolución le fuese favorable. Entre las resoluciones dictadas por la comisión arbitral figurará en todo caso la proposición en que cada una de las partes deberá participar en el abono de los horarios de las personas que forman la comisión y de los peritos cuyo informe haya sido solicitado por ella.
