Abstract:
A microcomputer is configured to perform a first control and a second control. The first control is of: starting operation of a power converter, when a first power supply voltage exceeds a starting voltage; and stopping the operation of the power converter, when the first power supply voltage is below a maintaining voltage. The second control is of: switching off a second switching element, when a second power supply voltage exceeds a first threshold voltage; maintaining an off-state of the second switching element until the second power supply voltage is below a second threshold voltage; and switching on the second switching element, when the second power supply voltage is below the second threshold voltage.
