Abstract
Disclosed is a vehicle-used power supply system. The vehicle power supply system comprises a storage unit, a bidirectional dc/dc convertor, a dc bus, a controller and a driving module. The bidirectional dc/dc convertor is configured to boost the power stored in the storage unit to a dc bus power. The controller is configured to control the bidirectional dc/dc convertor to operate in a boost mode for driving the motor or in a buck mode for charging the storage unit. The driving module is configured to receive the dc bus power and drive the motor.
Claims8
A vehicle-used power supply system including:
- an energy storage unit 105;
- a direct current bus 14;
- a bi-directional power converter 13 electrically connected to the energy storage unit 105 and the direct current bus 14, wherein the bi-directional power converter 13 includes a coupling inductor, wherein the bi-directional power converter 13 boosts electricity from the energy storage unit 105 and provides direct current bus electricity to the direct current bus 14;
- a controller 173 electrically connected to a motor 40 and the bi-directional power converter 13, wherein the controller 173 provides a first control signal and a second control signal based on the operation of the motor 40 and the output of the electricity from the energy storage unit 105, wherein the first control signal controls the bi-directional power converter 13 to switch between a boost mode and a reduction mode;
- and
- a drive module 171 electrically connected to the direct current bus, the controller and the motor, wherein the drive module 171 receives the direct current bus electricity and controls the rotational speed of the motor 40.
