An Active Power Decoupling Quasi-Z-Source Cascaded Multilevel Inverter Conference Paper uri icon

abstract

  • 2016 IEEE. An active power filter (APF) integrated quasi-Z-source cascaded multilevel inverter (qZS-CMI) is proposed in this paper. The purpose of incorporating the APF is to independently divert the second-order harmonic (2) power from dc side to APF's capacitor, for each of the cascaded single-phase quasi-Z-source inverter (qZSI) modules. The APF capacitor allows highly fluctuated ac voltage and current, with a small capacitance. The each module's qZS inductors and capacitors only handle the switching-frequency voltage and current ripple. Thus, the impedance values are as small as a three-phase qZSI, avoiding bulky inductors and capacitors in high-power applications. Operating principle and 2 power buffering ability of the APF integrated qZS-CMI are analyzed. Design of the APF circuit parameters is illustrated. Simulation results demonstrate the validity of the proposed approach.
