A three-phase diode bridge rectifier is fed from a 400 V RMS, 50 Hz, three-phase AC source. If the load is purely resistive, then peak instantaneous output voltage is equal to
A three-phase diode bridge rectifier is fed from a 400 V RMS, 50 Hz, three-phase AC source. If the load is purely resistive, then peak instantaneous output voltage is equal to
Right Answer is:
√2 × 400
SOLUTION
Given
RMS voltage = 400 V
Peak voltage or Maximum voltage = √2.RMS
Peak voltage = √2 × 400
