A bidirectional power converter includes a first terminal (11; 111a, 111b, 111c), a second terminal (13; 113a, 113b, 113c), a main reactor (22; 122a; 122b; 122c), a plurality of sub-circuits (5, 6) and a controller. The sub-circuits each include an upper switching element (32, 34), a lower switching element (31, 33), two diodes (42, 41), and a sub-reactor (24). 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 (5, 6), 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.
