Abstract
The present invention relates to a vehicle power control device and method capable of reducing a size and manufacturing cost of a circuit. The vehicle power control device according to an embodiment of the present invention includes a closed loop buck-boost converter supplied with power from a power source and outputting the power to a load a plurality of open loop converters connected to the closed loop buck-boost converter in parallel and supplied with the power from the power source and outputting the power to the load and a controller controlling an operation of the closed loop buck-boost converter and an operation of the plurality of open loop converter, respectively, depending on power capacity required for the load.
Claims19
A vehicle power control device, comprising:
- a closed loop buck-boost converter supplied with power from a power source and outputting the power to a load;
- at least one open loop converter connected to the closed loop buck-boost converter in parallel and supplied with the power from the power source and outputting the power to the load;
- and
- a controller controlling an operation of the closed loop buck-boost converter and an operation of the at least one open loop converter, respectively, depending on power capacity required for the load,
- wherein the controller controls the closed loop buck-boost converter to be maintained in an operating state.
