A three-port charger with an inversion function includes a primary side conversion circuit connected with a primary side winding of a transformer, a secondary side first conversion circuit connected with a second winding of the transformer, a secondary side second conversion circuit connected with a third winding of the transformer and a fourth winding of the transformer which are connected in series, and a central control unit used for controlling switches in the primary side conversion circuit, the secondary side first conversion circuit and the secondary side second conversion circuit. The primary side conversion circuit is connected with an external power supply, the secondary side first conversion circuit is connected with a high-voltage battery. The secondary side second conversion circuit is connected with a low-voltage load. The present invention integrates the independent charger and a high-power DCDC module, and shares a power switch, a control circuit and a magnetic core.
