基于DSP控制的电压型PWM整流器

摘要

According to the work principle of the PWM rectifier, this paper analyzes its control method. Through the hysteresis control of the current, it builds a two closed loop automation system of the voltage source PWM rectifier with TMS 320F2812 as the controller. Experiment results show that the system has good static per- formance and dynamic performance and provides a theoretical foundation for designing PWM rectifiers.%根据PWM整流电路的工作原理,分析了PWM整流控制方式,采用滞环电流控制方式,以TMS320F2812为控制器组建了电压型PWM整流器双闭环自动控制系统。实验结果表明,该系统具有良好的静态、动态性能。为设计PWM整流器提供了一定的理论依据。
