Electronic device and control method

An electronic device comprising:

• a first control unit;
• a voltage conversion unit that converts the voltage supplied from a power supply device into an output voltage, depending on a voltage of a battery;
• a power supply unit that uses power supplied from the power supply device to charge the battery and supply power to the first control unit;
• and
• a second control unit that (i) controls the power supply unit to supply power to the first control unit without passing through the voltage conversion unit, in a case where a difference between the voltage supplied from the power supply device and the voltage of the battery is smaller than a predetermined value, and (ii) controls the power supply unit to supply power to the first control unit via the voltage conversion unit, in a case where the difference between the voltage supplied from the power supply device and the voltage of the battery is greater than the predetermined value.

A method comprising:

• controlling a power supply unit of an electronic device to supply power to a control unit of an electronic device via a voltage conversion unit, in a case where a duty of PWM (pulse width modulation) control exceeds a predetermined threshold;
• and
• controlling the power supply unit to supply power to the control unit without passing through the voltage conversion unit, in a case where the duty of PWM control is less than the predetermined threshold,
• wherein the voltage conversion unit converts a voltage supplied from a power supply device into an output voltage, depending on a voltage of a battery, and
• wherein the power supply unit uses power supplied from the power supply device to charge the battery and supply power to the control unit.

A method comprising:

• controlling a power supply unit of an electronic device to supply power to a control unit of the electronic device without passing through a voltage conversion unit of the electronic device, in a case where a difference between a voltage supplied from a power supply device and a voltage of a battery is smaller than a predetermined value;
• and
• controlling the power supply unit to supply power to the control unit via the voltage conversion unit, in a case where the difference between the voltage supplied from the power supply device and the voltage of the battery is greater than the predetermined value,
• wherein the voltage conversion unit converts a voltage supplied from the power supply device into an output voltage, depending on a voltage of a battery, and
• wherein the power supply unit uses power supplied from the power supply device to charge the battery and supply power to the control unit.
