Abstract
Described herein are systems, devices, and methods for a wireless energy transfer source that can support multiple wireless energy transfer techniques. A wireless energy source is configured to support wireless energy transfer techniques without requiring separate independent hardware for each technique. An amplifier is used to energize different energy transfer elements tuned for different frequencies. The impendence of each energy transfer element is configured such that only some of the energy transfer elements is active at a time. The different energy transfer elements and energy transfer techniques may be selectively activated using an amplifier without using active switches to select or activate different coils and/or resonators.
