摘要
The bi-directional DC/DC converter has zero voltage switching (ZVS) soft switching capability resulting in a higher efficiency, and provides reduction of the switching losses due to higher switching frequencies. The capability of operation in higher frequencies results in reducing the size of passive components including inductance and capacitors. The subject DC/DC converter is capable of operating with three voltage levels in both power flow directions, thus providing flexibility in the voltage control and attaining lower inductor current ripple and lower switch voltage ratings. DC link capacitors are replaced with ultra capacitor banks split in two.
