Abstract
A bidirectional power converting device coupled between first and second power storage units includes: a coupling circuit including a first winding coupled to the first power storage unit, and a second winding coupled in series to the first winding; first and second switches coupled to the first winding; a capacitor coupled between the first and second switches; a third switch coupled between the second winding and the capacitor; and a fourth switch between the second winding and the second power storage unit. The first, second, third and fourth switches are operable so that an input voltage supplied by one of the first and second power storage units is converted into an output voltage that is to be supplied to the other one of the first and second power storage units.
