A Zero-Voltage-Transition Bidirectional DC/DC Converter

IEEE Transactions on Industrial Electronics, 2015
A three-level (TL) bidirectional dc/dc converter is a suitable choice for power electronic systems with a high-voltage dc link, as the voltage stress on the switches is half and inductor current ripple frequency is twice the converter's switching frequency.
