摘要

对具有直流升压和降压特性的整流系统进行了研究。该系统由一个PWM电压源整流器和一个级联的dc - dc降压变换器组成。理论上，该系统可以产生从零伏到无穷大的直流输出电压和正弦交流输入电流，并且位移功率因数可以保持在一个单位。该系统可实现双向潮流。提出了基于正弦内模的控制策略。两个PS稳压器和两个PI稳压器用于每个控制对象。实验结果证实了所提控制系统的有效性。

Sinusoidal internal model based control of a three-phase voltage source rectifier with buck-boost operation

A rectifier system having a DC voltage step-up and step-down characteristic is treated. The system consists of a PWM voltage source rectifier and a DC-to-DC buck converter connected in cascade. Theoretically, the system can produce a DC output voltage ranging from zero volts to infinity and a sinusoidal AC input current, and the displacement power factor can be kept at unity. The system can perform bidirectional power flow. Control strategy based on a sinusoidal internal model is proposed. Two PS regulators and two PI regulators for each control object is used. Experimental results confirm the validity of the proposed control system.
