Claims16
A multi-input wireless power supply comprising:
- an AC/DC rectifier circuit capable of accepting a first input voltage or a second input voltage, wherein said AC/DC rectifier produces a rectified output;
- a sensor for detecting which of said first input voltage and said second input voltage is connected to said multi-input wireless power supply;
- a plurality of switching circuits each coupled to said rectified output;
- a first tank circuit coupled to one of said plurality of switching circuits, wherein characteristics of said first tank circuit are selected for transferring power to a remote device as a function of said first input voltage;
- a second tank circuit coupled to a different of said plurality of switching circuits, wherein characteristics of said second tank circuit are selected for transferring power to said remote device as a function of said second input voltage, wherein said characteristics of said second tank circuit are different from said characteristics of said first tank circuit;
- a low power DC/DC converter coupled to said AC/DC rectifier for converting said rectified output;
- a microcontroller coupled to said low power DC/DC converter, wherein said microcontroller is programmed to control said plurality of switching circuits based on output from said sensor.
