A charger, comprising a controller (1), an alternating-current-side capacitor assembly (2), a power factor correction circuit (3), a bus capacitor assembly (4), and a DC-DC converter (5). The bus capacitor assembly (4) comprises a first capacitor (C1) and a second capacitor (C2). The alternating-current-side capacitor assembly (4) is connected to both the first capacitor (C1) and the second capacitor (C2). When the charger is in a single-phase alternating-current charging mode, the controller (1) is used to dynamically adjust an on-duty ratio of a high-frequency bridge arm of the power factor correction circuit (3) according to the voltage of an alternating current, so as to discharge the voltage of the alternating-current-side capacitor assembly (4), perform power factor correction on the alternating current, and input a direct current outputted from the power factor correction circuit to the DC-DC converter (5). Also provided are a charger control method and a vehicle.
