Project 1

PART A :- Three-phase diode rectifier

1. Average dc voltage output = 272.05 volt

1. peak-to-peak ripple= 2.3 volt

2. input current THD=91.91%

3. DPF and PF calculations are below :-

4. average dc current= zero because waveform is symmetrical in nature

PART B :- Three-phase thyristor converter

1 ) Is1 = 9.851 amps

2) Is = take the all values square and square roots = 10.514

below is the source current wave form

3) DPF= cos(9.5181)=0.9860

4) PF = DF * DPF = 0.91126*0.9860

5) % THD= 124.13%
