where V r is the cut-in voltage of the diode. Half wave rectifier circuit requires only one diode. | EduRev Electrical Engineering … Dec 28,2020 - For a half wave or full wave rectifier the Peak Inverse Voltage of the rectifier is alwaysa)Greater than the input voltageb)Smaller than the input voltagec)Equal to the input voltaged)Greater than the input voltage for full wave rectifier and smaller for the half wave rectifierCorrect answer is option 'B'. Half wave rectified alternating current is one which flows for half the time during one cycle. Peak inverse voltage is given as PIV >= 2V m. If, at any point, PIV
