Abstract
A charging circuit is provided. The charging circuit is applied to an electronic device. The charging circuit includes a resonant circuit and a voltage transformer circuit. The resonant circuit is configured to convert a received DC signal into an AC signal. The voltage transformer circuit includes a primary winding and a secondary winding. The primary winding is connected to an output end of the resonant circuit. The primary winding is coupled to the secondary winding. The voltage transformer circuit is configured to transform a first voltage of the AC signal into a second voltage through the primary winding and the secondary winding. The second voltage is configured to supply electrical energy to an electricity-consuming apparatus. The second voltage is less than or equal to the first voltage.
