摘要
针对三相-单相矩阵变换器系统,提出了一种新型调制策略,即将虚拟整流级的空间矢量调制(Space Vector Pulse Width Modulation,简称SVPWM)和虚拟逆变级的正弦脉宽调制(Sine Pulse Width Modulation,简称SPWM)相结合进行控制,通过简单的调制合成即可实现输出电压正弦。研制了基于四步半软换流策略的1 kW三相-单相矩阵变换器实验样机,实验结果验证了所提控制策略的可行性和正确性。
A new modulation strategy is proposed for three-phase to single-phase matrix converter,which combines the virtual rectifier-level space vector pulse width modulation（SVPWM）and virtual-level sine pulse width modulation（SP-WM）inverter to realize sinusoidal output with input voltages detection and simple calculation.A 1 kW three-phase to single-phase prototype is built based on four-step commutation.The experiments results show the validity and reliabili-ty of the proposed control strategy.
