Abstract
A system and method for use in matching a source to a dynamic impedance electrical load is described. The system may include a zero voltage switching amplifier and a variable signal generator, where the zero voltage switching amplifier is in communication with a resonant load. The system also includes a microcontroller for executing an algorithm that causes the microcontroller to locate a resonant frequency of the resonant load by sampling frequencies by changing a frequency of the variable signal generator and recording sensor data, and then correlating the collected sensor data (minima) to the resonance.
