摘要
提出一种新型开关耦合电感准Z源逆变器,实现相同输入电压和直通占空比条件下逆变器输出电压的大幅提升。分析了新拓扑的工作机理、升压特性和控制策略,采用简单升压控制方法,通过Matlab仿真试验验证了新拓扑的可行性。
A new type of switch coupled induction quasi-Z-source inverter is put forward, with realizing of dramatic increase of inverter output voltage under conditions of same input voltage and shoot-through duty ratio. The paper analyzes the working mechanism, boosting characteristics and control strategies of new topology, verifies the feasibility of new topology by means of simple boosting method and by application of Matlab simulation test.
