摘要 对矩阵式电力变换器的几种控制策略进行了比较,分析了直接变换法、间接变换法和滞环电流踉踪法的基本原理和电压传输比。把矩阵变换器等效成一个虚拟的整流器和一个虚拟的逆变器,以虚拟逆变器为例,介绍了电压空间矢量脉宽调制(VSVPWM)技术的控制策略,并进一步探讨了实现这些控制策略的安全换流问题、开关损耗问题和谐波抑制问题。 Several control strategies of matrix power converter are compared. The basic principles and voltage transfer ratios of direct commutation. indirect commutation and hysteresis-band current tracking methods are analyzed. Matrix converter is equivalent to a virtual rectifier and a virtual inverter. A control strategy of voltage space vector pulse width modulation (VSVPWM) technique is introduced by taking the virtual inverter as an example. Furthermore, how to realize those strategies of safe commutation, switching losses and harmonics restrain issues are discussed.
