If Vdc1 is the dc output voltage in half wave controlled rectifier circuit feeding resistive load and Vdc2 is the dc output voltage in full wave controlled rectifier circuit (M - 2 connection) feeding resistive load, then
A semi converter operates in two quadrants.
Figure shows a chopper feeding RLE load, The free wheeling diode conducts when
Assertion (A): An ideal rectifier should have unity harmonic factor
Reason (R): An ideal rectifier should have unity displacement factor.
A single phase half wave rectifier is feeding a resistive load. When a = 0, dc output voltage is 127 V. When a = 30°, the dc output voltage will be about
