Abstract:
The present disclosure relates to a driving circuit and a wireless power transmitter including the same. In view of the fact that a transmitter-side coupling circuit exhibits a high resistance when an AC current having a frequency far away from its operating frequency is applied to input terminals, the present disclosure connects a plurality of transmitter-side coupling circuits which operates at different operating frequencies in parallel at output terminals of the same inverting circuit. The controller controls an operating frequency of the AC current output from the inverting circuit to drive different one of the transmitter-side coupling circuits to operate. Thus, one driving circuit can drive the transmitter-side coupling circuits which operate at different operating frequencies or under different technical standards to supply electric energy. The driving circuit is compatible with wireless power receivers which operate at different operating frequencies, and thus has improved compatibility.
