摘要

提出了一种单额定电感拓扑的电流源多电平逆变器(CSMLI)。多电平逆变器由于减小了dv/dt、di/dt应力，对于降低输出电压和输出电流中的谐波畸变非常有效，是功率变换器应用中最熟悉的。对所设计的九电平电流源逆变器在对称和不对称工作模式下进行了测试，并采用多载波PWM(脉宽调制)策略的PI和模糊PI(比例积分)控制器对其活动进行了比较。对所提出的变换器进行了MATLAB/Simulink仿真，获得了其性能指标。实验结果验证了电流源多电平逆变器的有效性。

Analysis of Symmetrical and Asymmetrical Current Source Multilevel Inverter

The paper proposes a Current Source Multilevel Inverter (CSMLI) with single rating inductor topology. Multilevel inverters are most familiar with power converter’s applications due to reduced dv/dt, di/dt stress, and very efficient for reducing harmonic distortion in the output voltage and output current. The proposed nine-level current source inverter has been tested under symmetrical and asymmetrical modes of operation, and their activities are compared using PI and Fuzzy PI (Proportional Integral) controllers with multicarrier PWM (Pulse Width Modulation) strategy. MATLAB/Simulink simulation has been made for the proposed converter to obtain its performance measures. Some experimental results are given to verify the presented Current Source Multilevel Inverter.
