Switching Method to Minimize the Current Ripple of 3-Phase Interleaved Bidirectional DC-DC Converter in Light Load Operation Jung, Jae-Hun; Nho, Eui-Cheol;
This paper deals with a switching method to minimize the current ripple component of 3-phase interleaved bidirectional DC-DC converter for charging and discharging of the battery. The characteristics of the output current ripple in 3-phase and 2-phase operation modes according to the variation of battery voltage is analyzed and a phase conversion method for minimizing the magnitude of the current ripple is proposed. The proposed method can extend the light load range because the switching frequency is lower than that of a 3-phase operating system. Simulation and experimental results show the usefulness of the proposed method.
