摘要

提出了一种用于三相z源逆变器的空间矢量脉宽调制(SVPWM)新技术。所提出的改进SVPWM在有功和零态之外增加了一个通射状态,用于提高逆变器直流链路电压。穿透状态均匀地分配到零状态内的每个相位。因此,零电压周期缩短,产生穿透时间,有功状态不变。仿真和实验结果验证了新特性。

A novel space vector PWM for Z-source inverter
This paper presents a novel space vector pulse width modulation (SVPWM) technique for three phase Z-source inverter. The proposed modified SVPWM has an additional shoot-through state for boosting the dc link voltage of the inverter beside active and zero states. The shoot-through states are evenly assigned to each phase within zero state. So zero voltage period is diminished for generating a shoot-through time, and active states are unchanged. Simulation and experimental results are presented to demonstrate the new features.
