摘要： 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.

摘要： The present disclosure relates to a power transmitter, a resonance-type contactless power supply and a control method. The resonance-type contactless power supply adjusts a phase difference of an inverter control signal in a current cycle in a manner the same as that in a previous cycle in a case that a power parameter in the current cycle and that in the previous cycle satisfy a predetermined relationship, and adjusts the phase difference of the inverter control signal in the current cycle in a manner opposite to that in the previous cycle in a case that the power parameter in the current cycle and that in the previous cycle don't satisfy the predetermined relationship. The power parameter represents system efficiency. Thus, a suitable input current or voltage of the transmitter-side resonant circuit is determined by scanning actually, so that the system can operate at optimal efficiency.
