The invention relates to the field of motor windings of vehicle-mounted chargers, in particular to a parallel connection method and series connection method for motor windings of a three-phase non-isolated integrated vehicle-mounted charger. The purpose is to solve the problems that when the connecting mode of existing motor windings is changed, as a motor needs to be wired again to lead out middle points of the windings of all phases, the external connecting mode of the motor windings is complex; when currents flow through the existing motor windings, a motor rotor rotates to cause loss and noise. By the adoption of the parallel connection method and series connection method for the motor windings, the two windings are connected in series and then connected between a three-phase alternating-current power source and a rectifier bridge of the vehicle-mounted charger, or the two windings are connected in parallel and then connected between the three-phase alternating-current power source and the rectifier bridge of the vehicle-mounted charger. The parallel connection method and series connection method is used for connecting the motor windings into the vehicle-mounted charger.
