Half Wave Rectifier Analysis

The Half wave rectifier is a circuit, which converts an ac voltage to dc voltage.

The Transformer in the Half wave Rectifier can be used to obtain the desired level of dc voltage (using step up or step down transformers).

The primary of the transformer is connected to ac supply. This induces an ac voltage across the secondary of the transformer.

During the positive half cycle of the input voltage the polarity of the voltage across the secondary coil , forward biases the diode.

As a result a current IL flows through the load resistor, RL. The forward biased diode offers a very low resistance and hence the voltage drop across it is very small.

Thus the voltage appearing across the load is practically the same as the input voltage at every instant.
