基于不等幅载波APODPWM的电容电压自平衡七电平逆变器

In this article, a seven-level inverter based on bridge modular switched-capacitor circuits is presented. The inverter cannot only obtain dc–dc boosting conversion ability but also own capacitor voltage self-balance capability. Meanwhile, some of the switches can be operated under line voltage frequency, which makes the control strategy simpler and reduces the switching loss. More importantly, a n...
