Current Ripple Reduction for Cascaded H-bridge Converter with Phase-Shifted Carrier PWM
This paper proposes a new method to reduce the output current ripple in Cascaded H-bridge converter with Phase-Shifted Carrier PWM. The proposed technique introduces a new technique, namely Carrier Phase Angle Offset (CPAO), which changes the phase shift of the carriers between the phase legs of the converter. The mathematical analysis of the proposed technique is presented. Simulation results is provided to verify the theoretical analysis. The results show the proposed technique significantly reduces both the peak-to-peak and RMS current ripple.
