Abstract

Techniques for reducing harmonic distortion in single-switch three-phase boost rectifiers are presented. Optimal pulse-width modulation methods for the main switch to minimize input harmonic current distortion or to maximize the converter power range are described first. Effects of the voltage control loop on the input current waveform are then investigated by using the harmonic balance method. It is found that through proper design of the voltage controller, the input current harmonics in the closed-loop controlled system can be reduced to almost the same level as when the optimized PWM is applied. Simulation and experimental results are included to validate the analysis
