Two -way DCDC converter

The utility model relates to a two -way DCDC converter. The converter includes: the input links to each other with high voltage port, the output links to each other with low voltage port, adoption SAC topological structure's owner alternaties the module, with the main continuous controller of module that alternaties. The controller is used for alternateing the mode of module according to load direction switching owner, is the load, when high voltage port is the power, mainly alternaties module work in isolated step -down mode as low voltage port, when low voltage port was power, high voltage port for the load, the controller made the owner alternate module work in the isolated mode of stepping up. The utility model discloses a set up the owner and alternate module and controller, can be according to load direction automatic switch -over DCDC's the direction of current flow. Main transform module adopts sinusoidal amplitude switch technology, and work makes the energy loss of converter minimum at high -frequen
