An electrically excited motor drive system is integrated with an on-board charger (OBC), so that a power supply circuit that is in an electric vehicle and that is configured to drive an electrically excited motor can be integrated with an OBC of a dual active bridge (DAB) type. When a control component controls a switch circuit, the electrically excited motor drive system obtained after integration can separately implement a function of the power supply circuit or a function of the charging circuit in different working modes. In addition, when the electrically excited motor drive system is in different working modes, some circuits are further reused through time division. This addresses a problem that the power supply circuit cannot be integrated with the OBC of the DAB type, to reduce circuit complexity and costs of the electric vehicle.
