WebbA half wave rectifier is defined as a type of rectifier that only allows one half-cycle of an AC voltage waveform to pass, blocking the other half-cycle. Half-wave rectifiers are used to convert AC voltage to DC voltage, and only require a single diode to construct. A rectifier is a device that converts alternating current (AC) to direct ... WebbWhy PIV should be less than the break down voltage? The diode is a unidirectional device, hence if a voltage more than PIV is applied across the diode, an avalanche breakdown occurs. When this happens, the potential barrier is broken and a high impulse current flows in the circuit. This can damage the diode and the whole equipment as well.
