Abstract
A smart power adaptor and a method of controlling power supply thereof are provided. The smart power adaptor includes a power conversion circuit and a control unit. The power conversion circuit is configured to convert an alternating current (AC) power into a direct current (DC) power for providing to a load device. The control unit is coupled to the power conversion circuit. The control unit is configured to apply a corresponding power-supply control mean according to a power state through communication of a charging communication protocol of a battery module of the load device to control an operation of the power conversion circuit, so that the power conversion circuit uses different power conversion behaviors to generate the DC power in response to changing of the power status.
