This proposed work has two converters connected in cascade to have output voltage 4 times of input voltage. This converter is a non-isolated boost converter, which can level up Dc voltage from 24 Vdc input voltage to 120 Vdc output voltages. This is adequate suitable in order to develop and apply with any dc output renewable energy source, such as pv generation system etc. The proposed converter has totally four modules of Dc boost converter, which are connected in parallel. At the same time, the switching devices are controlled by 90 degree shifting, due to an interleaving technique. This will lead to a smoother output dc current. Two modes of operation are available for interleaved boost converter: Half mode and Full mode operation. Based on the power loss efficiency of the converter the reliability of the converter can be calculated. In an interleaved boost converter high reliability is present and increase in power will lead to a decrease in the reliability.

I. INTRODUCTION The solar cell can transform the energy from light source into an electrical dc source. By connecting a load to the system, the current will flow into an electrical circuit. In order to increase the power processing capability and to improve the reliability of the power electronic systems interleaved converters are used. This system is used to calculate the reliability of interleaved boost DCDC converter and presents a comparison with the reliability of the conventional boost converter. DC converter have a good reliability in long time operation. The failure rate and the power loss effect on the interleaved converters are calculated. The system should be small in size in order to ease installation, maintenance, power lossless, and toughness. The advantages of reliable products beyond the current state of the art. The military forces and space programs have resulted in a need for vastly improved reliability in machinery components. This paper concentrate the reliability of interleaved boost dc–dc converter and presents a comparison with the reliability of the conventional boost converter. Two different operation modes are used (half-power and full-power operation) are used for the interleaved converter. Also the power loss effect on components and on the reliability of converters is discussed. A two- modes are used for interleaved boost converter. The Double dual boost converter was analysed and this double dual boost converter increase the voltage gain and the system reliability. A two-phase interleaved boost converter is used as critical conduction mode power factor corrector, which uses as variation-tolerant phase shifter to ensure accurate 180° phase shift between the two interleaved converters. Application of interleaved dc–dc boost converters for the photovoltaic generation system. Their features are continually being improved, power devices MOSFET, insulated gate bipolar transistor ((IGBT) diode, etc. remain clearly the weakest components in a power converter. The failure mode considered here is a permanent fully on-state mode of the devices that will be modelled by an ideal short-circuit state. A capacitors are widely used for dc links in power converters to balance instantaneous power difference between the input source and output load, and minimize voltage variation in the dc link. In some applications, they are also used to provide sufficient energy during the hold-up time.
