Abstract
An electronic device includes a first control unit, a voltage conversion unit, a power supply unit, and a second control unit. The voltage conversion unit converts the voltage supplied from a power supply device into an output voltage, depending on a voltage of a battery. The power supply unit uses power supplied from the power supply device to charge the battery and supply power to the first control unit. The second control unit controls the power supply unit, to supply power to the first control unit via the voltage conversion unit, in a case where a duty of PWM control exceeds a predetermined threshold, and to supply power to the first control unit without passing through the voltage conversion unit, in a case where the duty of PWM control is less than the predetermined threshold.
