摘要

本文报道了一种新的五电平脉宽调制(PWM)，其中包括一个由升压/反激DC-DC转换器提供的飞行电容器，该电容器还提供直流母线电压。实现传统的五电平飞行电容逆变器所需的功率器件和电容器数量显著减少。该拓扑不需要复杂的PWM控制来调节电容器电压，并且能够在任何功率因数条件下工作。仿真和实验结果验证了该变换器的原理。

New Five-Level Flying Capacitor Inverter Fed by a Boost-Flyback DC-DC Voltage Source

This paper reports a new five-level pulse-width modulation (PWM) that includes a flying capacitor supplied by a boost/flyback DC-DC converter that also provides the DC-bus voltage. There is a significant reduction in the number of power devices and capacitors required to implement a conventional five-level flying capacitor inverter. The topology is free from complex PWM control to regulate the capacitor voltage and is capable of operating under any power factor condition. Simulated and experimental results validate the converter principle.
