摘要

交流电形式的电能可以用整流器转换成直流电。与二极管和可控硅整流器相比，三相脉宽调制整流器具有双向功率流，统一功率因数，直流链路电压控制等优点。本文采用基于空间矢量脉宽调制的矢量控制技术对PWM整流器的直流电压和单位功率因数进行控制。对系统进行了暂态分析。利用MATLAB对200V, 3φ PWM整流器进行仿真，验证控制方法。利用DSP TMS320F28069实现了一种3φ PWM整流器样机，并给出了实验结果。

Hardware implementation of 3-Φ PWM rectifier using DSP

Electrical energy in the form of alternating current can be converted to direct current using rectifiers. Three phase pulse width modulated rectifiers compared to diode and thyristor rectifiers offer advantages like bidirectional power flow, unity power factor, control of DC-link voltage etc. This paper deals with control of DC voltage and unity power factor operation of PWM rectifier using Space Vector Pulse Width Modulation based Vector Control technique. A transient analysis of the system is carried out. A 200V, 3φ PWM rectifier is simulated using MATLAB to verify and validate control method. A prototype of 3φ PWM rectifier is implemented using DSP TMS320F28069 and results obtained are presented.
