Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress a loss caused by a filter, and an increase in circuit scale in a power supply device.SOLUTION: A power supply device 100 comprises: a switching power source 101 which performs power conversion of power supplied from an input power source and supplies the resultant power to a power storage device; a switching power source 104 which performs power conversion of power supplied from the switching power source 101 or power storage device and supplies the resultant power to a load device; a noise filter 106; and a shield 108 which covers the switching power source 101, the switching power source 104 and the noise filter 106. The noise filter 106 is provided at a power storage device side with respect to a branch point where a power line from the switching power source 101 to the power storage device crosses a power line from the switching power source 104 between the switching power source 101 and the power storage device and between the power storage device and the switching power source 104. When the first switching power source does not perform the power conversion, the second switching power source performs the power conversion.SELECTED DRAWING: Figure 3
