Half Wave Rectifier And Full Wave Rectifier Diagram. In half wave rectifier when the ac supply is applied at the input a positive half cycle appears across the load whereas the negative half cycle is suppressed this can be done by using the semiconductor pn junction diode. Working principle of half wave rectifier.
In order to build an efficient smooth dc power supply a full wave rectifier is always preferred. There is a large ac ripple voltage component at the source frequency for a half wave rectifier and twice the source frequency for a full wave rectifier. However for applications in which a constant dc voltage is not very essential you can use power supplies with half wave rectifier.
The half wave rectifier uses only a half cycle of an ac waveform.
Half wave rectifiers use one diode while a full wave rectifier uses multiple diodes. Rectifier broadly divided into two categories. While half wave and full wave rectification deliver unidirectional current neither produces a constant voltage. In half wave rectifier only half cycle of applied ac voltage is used.
