Abstract

This paper describe two PWM rectifier control using fixed-frequency SVPWM modulation. They are direct current control and direct power control based on the active and reactive power calculating. Comparative analyses are presented in the response speed, stability and harmonic content. It shows that direct current control system responses faster and is more stable. Total harmonic distortion value of direct current control is smaller. The reason that direct current control performs better is that there is feed forward decoupling in the system, thus it exhibits excellent features.
