Z源逆变器由电感和电容组成，结构简单，无需额外的开关元件，具有独特的升压能力。由于与传统逆变器相比Z源逆变器的复杂操作模式，使用普通空间矢量脉宽调制不能实现升压操作、轻负载和再生操作。本文提出了一种改进的SVPWM，来自已知的方程，以克服这一限制。此外，方程控制输出行为的所有工作模式，如降压，升压和再生操作，给出了详细的。最后给出了实验结果。
Z-source inverters, consisting of both inductors and capacitors as DC-link components, provide unique boost capability with simple structure needing no additional switching elements. Due to complex operation modes of the Z-source inverter compared to a conventional inverter, boost operation, light load and regenerating operation cannot be achieved using common space-vector pulse width modulation. This paper proposes a modified SVPWM, derived from the known equations, to overcome this limitation. Besides, equations to control the output behaviour for all operating modes, such as buck, boost and regenerating operation, are given in detail. Finally, experimental results are presented.
