Title:
VEHICLE POWER SUPPLY CONTROL CIRCUIT, VEHICLE CONTROL DEVICE, AND VEHICLE POWER SUPPLY CONTROL CIRCUIT CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/142235
Kind Code:
A1
Abstract:
This vehicle power supply control circuit is provided with: a first input terminal to which a voltage output by a DC-DC converter for performing voltage conversion on a power supply voltage is supplied; a second input terminal to which the power supply voltage is supplied; an output terminal that outputs a voltage for controlling a semiconductor element generating a drive current for a motor generator and having non-saturation region characteristics; a switching circuit having one end connected to the first input terminal and the other end connected to the output terminal, making the connection between the first input terminal and the output terminal conductive by being turned on on the basis of a signal applied to a control terminal, and, meantime, disconnecting the connection between the first input terminal and the output terminal by being turned off on the basis of the signal applied to the control terminal; and a switching control unit for controlling the switching circuit by applying the signal to the control terminal on the basis of the voltage at the second input terminal.
