The invention provides a charger, a vehicle, a charging method and a medium, and the charger, the vehicle, the charging method and the medium are low in cost and can reduce current ripples at a bus capacitor and improve charging quality. The charger comprises a power factor correction module, a bus capacitor module and a mode switching module. Wherein the power factor correction module can be used for rectifying a received target alternating current, and the target alternating current is a three-phase alternating current or a single-phase alternating current. The mode switching module can be used for conducting the third end of the power factor correction module and the first end of the bus capacitor module when the target alternating current is a three-phase alternating current, so that the power factor correction module, the positive bus, the bus capacitor module and the negative bus form a charging loop; or when the target alternating current is the single-phase alternating current, the third end of the power factor correction module is connected with the zero line, so that the power factor correction module, the positive bus, the bus capacitor module, the negative bus and the zero line form a charging loop.
