What are the values of peak inverse voltage PIV for a full wave rectifier using center tapped transformer and bridge rectifier for peak input voltage?

Peak inverse voltage (PIV) is 2Vmax in center tapped full wave rectifier (but it is Vmax in full wave bridge rectifier). By using a center tapped transformer we are creating two AC sources which are out of phase by 180° ( Vao and Vbo ) but with same amplitude of Vmax.

Why is the peak inverse voltage PIV important in rectifier circuits?

The importance of peak inverse voltage is shown in the reverse bias condition of the diode. If the PIV exceeds across the junction of the diode in reverse bias condition beyond the specified PIV rating, then the junction gets damaged or breakdown occurs. …

Why is PIV important in rectifier service?

PIV is the maximum voltage that should be applied to the diode in reverse bias. Diodes must have PIV rating that is higher than the maximum supplied voltage. Thus, PIV rating is important to know how much maximum voltage can be applied across the diode safely without damaging the diode.

Why PIV of bridge rectifier is VM?

The PIV (peak inverse voltage) ratings of the diodes in bridge rectifier is half than that of needed in a center tapped full wave rectifiers….Transformer Utilization Factor of Bridge Rectifier.

Parameters	Center tapped full wave rectifier	Bridge rectifier
Peak inverse voltage	2Vm	Vm
Vdc(no load)	2Vm/π	2Vm/π

What is PIV in full wave rectifier?

Peak Inverse Voltage (PIV): The maximum voltage across a reverse bias diode is known as Peak Inverse Voltage.

What is the PIV of half wave rectifier?

Half Wave rectifier: Vm

CIRCUIT	Number of Diodes	Peak Inverse Voltage (PIV)
Half-Wave Rectifier	1	V m
