Analysis of Full wave Rectifier. Peak Inverse Voltage: The peak inverse voltage of full wave rectifier is double to that of half wave rectifier. The PIV (Peak inverse voltage) across D1 is 2V smax and PIV across diode D2 is also 2V smax. It is double because the PIV across the diode in reverse biasing is the sum of the voltage across half of the secondary winding and load resistor.
