Abstract
A bidirectional power converter includes a first terminal, a second terminal, a main reactor, a plurality of sub-circuits and a controller. The sub-circuits each include an upper switching element, a lower switching element, two diodes, and a sub-reactor. The controller sequentially controls the sub-circuits such that: the lower switching element is turned on and turned off and then the upper switching element is turned on and turned off in each of the sub-circuits, while a current is flowing from the first terminal toward the second terminal; and the upper switching element is turned on and turned off and then, the lower switching element is turned on and turned off in each of the sub-circuits, while the current is flowing from the second terminal toward the first terminal.
