Why Are Transformers Used In The Rectifier Circuits? This is true that a rectifier is a device that allows the conductivity of current to flow in one direction; it is an AC to DC converter. There are many electronic devices that work in DC rather than directly working on AC, for such electronic devices an effective AC to DC converter is required. That is why transformers are used in cascade with the rectifiers. Our company Trutech Products is standing as the leading Rectifier Transformer Manufacturers In India, assure you the quality product as per industrial norms and standard. The circuits that include transistors are DC bias, and the transistor is the heart of the smart and intelligent circuits. Entire digital circuit’s works on DC voltage level that is on high or low logic level. For such advance circuit, direct AC needs to be converted into DC and that is why transformers are always used before the rectifiers in the digital circuits.
