Abstract
Official abstract text for this publication.
A power supply applied to an electronic device for providing power includes a transformer unit, a connector, a pulse-width modulation (PWM) control unit, and a switch unit. The connector is electrically connected with the secondary side of the transformer unit for outputting a first output voltage. The PWM control unit outputs a pulse signal with a first period. The switch unit is electrically connected between the PWM control unit and the primary side of the transformer unit. When the electronic device is connected to the power supply, the connector receives an external control signal, and the PWM control unit adjusts the pulse width of the pulse signal to a second period and transmits the pulse signal with the second period to the switch unit to control the connector to output a second output voltage to the electronic device.
