Title:
POWER SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2015136267
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power supply deice which allows for enhancement in the degree of freedom of power supply between a high voltage storage battery 60, each battery cell C1-C4 and a low voltage storage battery 70.SOLUTION: A power supply deice 100 includes first, second and third power converting sections 10, 20, 30, and a transformer 40. In the transformer 40, a high voltage side coil 40a, a low voltage side coil 40b and a cell side coil 40c are magnetically coupled each other. The first power converting section 10 is configured to be able to apply a DC voltage outputted from a high voltage storage battery 60 to the high voltage side coil 40a, while converting into an AC voltage. The second power converting sections 20 is configured to be able to apply an AC voltage outputted from a low voltage side coil 40b to a low voltage storage battery 70, while converting into a DC voltage. The third power converting section 30 is configured to be able to switch the cell side coil 40c and each battery cell C1-C4 between electrical conduction state and interruption state.
