Abstract
A power supply control device includes: a power conversion device; a controller; a current detection device; a comparison device configured to output a shut-off start signal when a value of current detected by the current detection device is larger than a preset current threshold value; a shut-off device configured to shut off, based on a shut-off control signal, a conversion operation signal; a latch device configured to output the shut-off control signal based on the shut-off start signal output by the comparison device and to perform, until a latch release signal is input, a latch operation, in which the shut-off device is caused to maintain a state in which a conversion operation signal is shut off; and a delay device configured to output a latch release signal after a delay time elapses, the delay time being determined by components of the delay device.
