ABSTRACT:
A contactless charging device and contactless charging method is provided. The contactless charging device includes an energy-storing device for providing a DC signal as an input power, a power module electrically connected to the energy-storing device for generating an output signal in response to the DC signal and a control signal. The power module includes a transformer primary winding for coupling the output signal to a transformer secondary winding located external to the contactless charging device. The charging device further includes a feedback controller electrically connected to the power module for generating the control signal in response to the output signal, a predetermined power and a predetermined phase. When the contactless charging device is in close proximity to a plurality of loads, the output signal at the transformer primary winding will be coupled to the transformer secondary windings of the plurality of loads so as to simultaneously charge the loads.
