Abstract: A controller for controlling a phase-shifted full-bridge circuit, a power supply module, and an electronic device. The phase-shifted full-bridge circuit includes a first leg and a second leg. A working state of the phase-shifted full-bridge circuit includes a first working state and a second working state. The controller is configured to: detect a load level of a load circuit coupled to the phase-shifted full-bridge circuit, and control, based on the load level, the phase-shifted full-bridge circuit to switch the running working state. When the phase-shifted full-bridge circuit runs in the first working state, the first leg is a leading leg, and the second leg is a lagging leg. When the phase-shifted full-bridge circuit runs in the second working state, the first leg is a lagging leg, and the second leg is a leading leg.
