Constant current power amplifier for MHz magnetic resonance wireless power transfer systems
This paper introduces the concept of constant current power amplifier (PA) for magnetic resonance wireless power transmitters, where the current output of the PA remains almost constant when the load impedance varies. The solution enables the wireless power transfer system to simultaneously support...

Summary: | This paper introduces the concept of constant current power amplifier (PA) for magnetic resonance wireless power transmitters, where the current output of the PA remains almost constant when the load impedance varies. The solution enables the wireless power transfer system to simultaneously support multiple devices and naturally supply the power demanded by receivers without feedback control. In this paper, the design methodology of such PA will be discussed in detail followed by a design example. |
