Question
A three-phase diode bridge rectifier is feeding a constant DC current of 100 A to a highly inductive load. If three-phase, 415 V, 50 Hz AC source is supplying to this bridge rectifier then the rms value of the current in each diode, in ampere, is _____________.
Correct answer
57 to 58
Solution
In a three-phase diode bridge rectifier each diode conducts for ( radians) out of a full cycle of ( radians).With a highly inductive load the DC current is constant, A, so the diode current is a rectangular pulse of height 100 A and width :Substituting A:The supply voltage of 415 V does not enter the calculation.Answer: A
