Charger

Abstract

A charger is provided. The charger includes: a first power input end, a second power input end, a power output end, a switching module, and a transformer. The switching module is separately connected to the first power input end and the second power input end. A primary side of the transformer is provided with a first resonant unit connected to the switching module. A secondary-side winding of the transformer is connected to the power output end. The switching module is capable of switching between a first on state and a second on state. When the switching module is in the first on state, input power at the first power input end is coupled to the secondary-side winding through the first resonant unit and is output through the power output end.
