摘　　要：阐述了电流型组合相移空间矢量脉宽调制(SVPWM)技术的基本原理和优点,该技术与组合相移正弦脉宽调制(SPWM)技术基本原理相同,但其电流利用率较高,且便于数字化实现。分析了电流型变流器基本工作原理,并依据组合变流器系统中变流器单元的工作特点提出了简单的基于d,q坐标的控制方案。最后进行了系统样机实验及数字仿真,结果证实了相移SVPWM技术的有效性和所提出的控制策略的正确性。The basic principle and merits of the multi-converter phase-shifted space vector pulse width modulation （SYPWM） technique are described.The technique has the same basic principle as multi-converter phase-shifted sinusoidal pulse width modulation （SPWM）, but it improves the current utilization factor around 15%, and it＇s easy for the digital implementation.This paper analyses the basic operation principle of the current-source converter and presents a simple d,q coordinate control scheme according to the operation features of current source multi-converter.The experimental and simulation results prove the validity and the feasibility of the proposed technique and the control scheme.
