摘要

本文介绍了两种采用定频SVPWM调制的PWM整流器控制方法。它们是基于有功和无功计算的直流控制和直接功率控制。从响应速度、稳定性、谐波含量等方面进行了对比分析。结果表明，直流控制系统响应速度快，稳定性好。直流控制的总谐波失真值较小。直流控制性能更好的原因是系统中存在前馈解耦，从而表现出优异的特性。

Comparison of Direct Current Control and Direct Power Control Using SVPMW Modulation

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.
