rectifier. It is never used in industrial applications because of its poor performance. In a single-phase half-wave rectifier‚ for one cycle of supply voltage‚ there is one half-cycle of output‚ or load‚ voltage. As such‚ it is also called single-phase one-pulse rectifier. Simulation is performed using R‚ RL and RLE load on the output side of the rectifier. (a) R load : The circuit diagram of a single-phase half-wave rectifier is shown in Fig.1. During the positive half cycle‚ diode is forward biased
