Title:
POWER SUPPLY APPARATUS AND STANDBY POWER SOURCE FOR CONTROLLER FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/179113
Kind Code:
A1
Abstract:
Provided is a power supply apparatus, comprising: an isolation drive unit comprising a high-voltage-side winding and a low-voltage-side winding and converting a high-voltage input from a high-voltage power source into a low-voltage output; a high-voltage input unit comprising a first switch section connected in series with the high-voltage-side winding of the isolation drive unit; an output control unit, a first terminal of which is connected to the low-voltage-side winding of the isolation drive unit, a second terminal of which is used for receiving an output enabling signal from the outside, and a third terminal of which outputs low-voltage power to be supplied when the output enabling signal is high; a switch regulation unit for outputting a switch regulation signal to the first switch section of the high-voltage input unit; a high-voltage starting unit, a first terminal of which is connected to the high-voltage power source, and a second terminal of which is connected to the switch regulation unit so as to provide a starting voltage to the switch regulation unit; and an auxiliary power source unit, a first terminal of which is coupled to the low-voltage-side winding of the isolation drive unit, and a second terminal of which is connected to the switch regulation unit, so as to provide power to the switch regulation unit.
