摘要

本文提出了一种新型单相3电平PWM逆变器，在与传统逆变器相同直流电源电压和开关频率的情况下，减轻了输出电压和电流的谐波分量。对其工作原理进行了分析，推导了开关函数。设计并实现了无差拍控制器，使逆变器即使在负载变化和滤波电感部分磁化的情况下也能保持输出电压的正弦波，并具有较高的动态性能。仿真和实验结果验证了该逆变器的有效性。

A novel high performance single-phase 3-level PWM inverter

This paper presents the novel single-phase 3-level PWM inverter to alleviate the harmonic components of output voltage and current under the conditions of identical supply DC voltage and switching frequency to the conventional inverter. The operational principles and analysis are performed and the switching functions are derived. The deadbeat controller is also designed and implemented for the inverter to keep the output voltage sinusoidal and to have high dynamic performances even in the cases of load variations and the partial magnetization in the filter inductor. The validity of the proposed inverter is proved from the simulated and experimented results.
