多电平逆变器在功率转换器应用中最受欢迎，这是由于开关上的dv/dt、di/dt应力减小以及谐波减少。提出了一种单额定电感拓扑的多电平电流型逆变器的电路结构。建议九电平电流源逆变器已被测试下对称和不对称的操作模式，为不同的负载，和他们的操作进行比较，使用PI和模糊PI控制器与多载波PWM策略。MATLAB/Simulink仿真已经进行了建议的逆变器，以获得其性能指标。
Multilevel inverters are most popular in power converter applications due to reduced dv/dt, di/dt stress upon the switches and reduced harmonics. This paper suggests a circuit configuration of multilevel current source inverter with single-rating inductor topology. The proposed nine-level current source inverter has been tested under symmetrical and asymmetrical modes of operation for different loads, and their operations are compared using PI and fuzzy PI controllers with multicarrier PWM strategy. MATLAB/Simulink simulation has been carried out for the proposed inverter to obtain its performance measures.
