A power conversion apparatus (10; 30) includes: a first power terminal (T11, T12); a switching circuit (13) including a first switching device (S1) on a path coupling a first power node (L11) to a first node (N1), a second switching device (S2) on a path coupling the first node (N1) to a second power node (L12), a third switching device (S3) on a path coupling the first power node (L11) to a second node (N2), and a fourth switching device (S4) on a path coupling the second node (N2) to the second power node (L12); a transformer (14; 34) including a first winding (14A) coupled to the switching circuit (13) and a second winding (14B); a rectifier circuit (15; 35); a second power terminal (T21, T22); and a controller (19; 39). The controller controls operations of the switching circuit and the rectifier circuit to supply power from the second power terminal toward the first power terminal during a predetermined period (PI) different from a period during which power is supplied from the first power terminal toward the second power terminal.
