Definitions
- the present invention relates to a power supply device mounted on a vehicle.
- the control device for a rotating electric machine described in Patent Document 1, cited below, includes an inverter that supplies power to the stator coil of the stator based on the output from a battery mounted on the vehicle, and a field current circuit that supplies power to the field winding based on the output from the battery.
- the inverter is configured with three legs according to the number of phases of the motor, and the field current circuit is configured with two legs that can change the direction of the current flowing through the field winding.
- Some batteries installed in vehicles are configured to be rechargeable from external power using a charger such as that described in Patent Document 2.
- the power supply device is characterized by comprising a motor drive unit including a field winding current supply unit that supplies current to the field winding of a wound field motor using DC power from a battery mounted on a vehicle, and an inverter that supplies current to a stator coil; an AC/DC conversion unit that converts AC power from an external source into DC power; and a converter that converts the DC power converted by the AC/DC conversion unit into DC power capable of charging the battery.
- the converter has a first conversion unit, a second conversion unit, and a transformer, the first conversion unit inputs the DC power from the AC/DC conversion unit to the primary winding of the transformer, the second conversion unit converts the AC power from the secondary winding of the transformer into DC power capable of charging the battery, and the field winding current supply unit and the second conversion unit are shared.
- the field winding current-carrying section which uses DC power from the battery to energize the field winding
- the second conversion section of the converter which converts AC power from the secondary winding of the transformer into DC power
- the field winding current-carrying section and the second conversion section are configured as the same circuit, sharing the field winding current-carrying section and the second conversion section can simplify the circuit configuration of the power supply device and reduce the number of parts. This makes it possible to make the power supply device lighter and more compact.
- FIG. 11 is a circuit diagram when the power supply device is used as a charger.
