ABSTRACT: 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.
