Title:
AUXILIARY POWER SOURCE DEVICE FOR VEHICLE AND OVERCURRENT PROTECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2013/080279
Kind Code:
A1
Abstract:
An auxiliary power source device for a vehicle is provided with a control section (10) and a resonant inverter circuit (1) that converts DC input to a desired AC voltage and delivers this as output. The control section (10) is provided with: a resonance time management section (13) that manages the resonance time of the current flowing in the resonant inverter circuit (1); a gate OFF instruction generating section (12) that, based on the detection current of a current detector (CT1), detects overcurrent flowing in the resonant inverter circuit (1) and if such overcurrent is detected, generates a gate OFF instruction for turning switching elements (HGU1, HGV2) of the resonant inverter circuit (1) OFF after lapse of the time at which the current flowing in the switching elements (HGU1, HGV2) initially becomes zero, based on the detection current of the current detector (CT1) and the resonance time, which is managed by the resonance time management section (13); and a gate signal generating section (14) that generates a gate signal that controls turning OFF of the switching elements (HGU1, HGV2) when the gate OFF instruction is input.
