Abstract :
The simulation of the rectifier circuits in a SPICE model is described, and the distorted line current waveforms and the spectrum of harmonic currents are shown. A reduction of harmonic content from the theoretical percentage was determined when the source impedance and the leakage inductance of a transformer are considered. The 12-pulse rectifier with 16.6% source reactance could reduce the 11th harmonic to 2.5%, which is less than MIL-STD-461 requirement.<>
