Abstract

An on-board charger (100) is configured in an electric vehicle (200) equipped with an on-board battery (200A). The on-board charger (100) includes an AC-to-DC conversion circuit (1), an energy storage capacitor (Cbusl), a bidirectional conversion circuit (2), an AC conversion circuit (3), and a controller (4). The AC-to-DC conversion circuit (1) converts a first AC power source (Pac1) into a DC power source (Pdc). The bidirectional conversion circuit (2) bidirectionally converts the DC power source (Pdc) and an energy storage power source (Pb), and charges or discharges the on-board battery (200A) according to the energy storage power source (Pb). The AC conversion circuit (3) selectively provides a second AC power source (Pac2) according to either the first AC power source (Pac1) or the DC power source (Pdc), and the controller (4) continuously controls the AC conversion circuit (3) to provide the second AC power source (Pac2) to a load (400) according to residual power of the on-board charger (100) during a hold-up time after a power interruption of the first AC power source (Pac1).
