摘要
混合型多电平逆变器是最近发展起来的一种多电平改进模式。本文根据混合型多电平逆变器电路结构实现方式的不同,将其分为混合电平式逆变器和混合单元式逆变器,分析了这两类逆变器电路拓扑结构的特点,提出了一种可有效克服高压单元功率器件电压应力、消除低压单元电流倒灌问题的设计方法。仿真实验证明了该方法是有效性。
This paper classifies the hybrid multilevel inverter into hybrid voltage inverter and hybrid cell inverter according to their to, pology structure, and analyzes their virtues and defects. A new design method is presented in this paper to resolve their problems of the over-abundance voltage stress of high-voltage cell and the current flowing backwards of the low-voltage cells, and its validity has been verified by simulation results.
