How can calculate the efficency of the rectifier. input
240V AC, current 5 amps,P.F 0.98, Output is 54 V DC,62.6 A.

Answer Posted / azeeem

I have a rectifier with the following conditions. I wanted to calculate efficiency.

For AC Input:
Voltage on AC = 380
Power Factor= 0.80
Amps on Phase 1 = 9.17
Amps on Phase 2 = 9.50
Amps on Phase 3 = 15.70

For DC Output:
VDC= 2.39
ADC= 1260

Thanks.
