ELECTRIFIED VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18099453 titled 'ELECTRIFIED VEHICLE
The abstract describes an electrified vehicle with a motor, a power factor correction circuit, and a DC/DC converter for efficient power management.
- The vehicle includes a motor with windings and a power factor correction circuit with AC and DC terminals.
- The power factor correction circuit has legs corresponding to the AC terminals and is connected between the DC terminals.
- The DC/DC converter has a first switching circuit connected to the battery terminals and a second switching circuit connected to the DC terminals.
- The converter switches between different legs to output the battery voltage to the motor or the DC terminals via a transformer.
- In battery discharging mode, the converter switches the primary and secondary legs to output the battery voltage to the DC terminals.
- When the motor is driven, the converter switches the primary legs to output the battery voltage to the motor.

Original Abstract Submitted
An electrified vehicle includes a motor including windings, a power factor correction circuit including AC and DC terminals and including legs corresponding to respective AC terminals and connected between the DC terminals, and a DC/DC converter including a first switching circuit including first, second, and third primary legs connected between terminals of a battery, a second switching circuit including at least one secondary leg connected between the DC terminals, and a transformer connected between the first and second switching circuits. In a battery discharging mode, the DC/DC converter switches the first primary leg and the at least one secondary leg, outputting a voltage of the battery to the DC terminals via the transformer. When the motor may be driven, the DC/DC converter switches the second and third primary legs electrically disconnected from the transformer, outputting the voltage of the battery to the motor.
