Bidirectional isolated DC-DC converter and operation method thereof

摘要

The present invention provides an input power supply, primary switches connected in parallel to the input power, a transformer having one end connected to the primary switches, secondary switches connected to the other end of the transformer, and the secondary side. Clamping switches connected to switches, clamping capacitors connected to the clamping switches, output inductors connected to the other end and secondary switches of the transformer and the clamping switches, and connected to the output inductors A control circuit for controlling at least one of the output power, the primary-side switches, the secondary-side switches, and the clamping switches, wherein the control circuit maintains a constant voltage of the clamping capacitor. A current source bidirectional isolated DC-DC converter for controlling the at least one switch and a control method thereof is disclosed.
