Third harmonic appearance in six pulse thyristor controlled rectifier supplying DC motor
Third harmonic appearance in six pulse thyristor controlled rectifier supplying DC motor
(OP)
HI
I am performing simulink simpower simulations of harmonic analysis of 5KW 440V 1000rpm dc motor fed by 6 pulse thyristor bridge.
for alpha of 75 degrees and different torque inputs the fft analysis of the ac current showing me third harmonics.
what is the reason for this ?
