Abstract

For the purpose of absorbing the inherent secondly ripple power (SRP) in two-stage inverter circuit (TIC), four-switch power decoupling circuit (FPDC) is proposed in this paper. FPDC can buffer the SRP on the ac-side of the inverter, realize the local decoupling of the pulsating power, and reduce the SRP loop in the system. Based on that, the corresponding pulse energy modulation (PEM) is designed to improve the operation performance of FPDC and further reduce the capacitance of the dc-side capacitor. Finally, the Simulink model and experimental platform are built to verify the effectiveness of FPDC and PEM control strategy.
