An apparatus for supplying power to a controller has a main power switch provided on a power supply path of a main power to a controller, a sub power switch provided on a power supply path of a sub power to the controller, and a power supply controller that opens the main power switch and closes the sub power switch so that the sub power is supplied to the controller when not receiving the main power. Accordingly, the power supply to the controller can be more stably switched. Additionally, an over-discharged battery is not used in power supply, and the controller can have a more stable reset operation.
