Title:
IN-VEHICLE POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/225397
Kind Code:
A1
Abstract:
The present invention suppresses the occurrence of a situation in which a driving unit used for precharging stops driving due to lowering of a power supply voltage. A power supply device (1) is provided with first voltage conversion units (21) and a control unit (88). The first voltage conversion units (21) perform a third voltage conversion operation for stepping up the voltage applied to a second conduction path (12) in accordance with providing a third control signal, by which an ON-signal and an OFF-signal are alternately switched, to a second drive switching element (42) and for applying an output voltage to a first conduction path (10) to which a capacitance component is electrically connected. The control unit (88) provides the third control signal to only some of the plurality of first voltage conversion units (21), thereby instructing the some of the first voltage conversion units (21) to perform the third voltage conversion operation.
