Abstract
A power supply method includes the following steps: detecting whether a battery is installed in a system; delivering a control signal to a power conversion circuit by a controller when it is determined that the battery is not installed in the system; turning on part of a plurality of transistors and turning off the other part of the plurality of transistors by the power conversion circuit according to the control signal and a reference signal, so that an input voltage is delivered to a receiving terminal of the system from a sending terminal of the system through a current path.
Claims3
A power supply method, comprising:
- detecting whether a battery is installed in a system;
- triggering a switch circuit by a set of triggering signals so as to conduct a current path when the battery is not installed in the system;
- sending a control signal to a power conversion circuit further by a controller when the battery is not installed in the system;
- controlling a plurality of first transistors by the power conversion circuit according to the control signal;
- and
- delivering an input voltage to a receiving terminal of the system from a sending terminal of the system through the current path by the system,
- wherein triggering the switch circuit by the set of triggering signals so as to conduct the current path comprises:
- turning on a second transistor on the current path by a first triggering signal included in the set of triggering signals and a reference signal;
- and
- turning on a third transistor on the current path by a second triggering signal included in the set of triggering signals.
