Abstract
A system and method for use in matching a source to a dynamic impedance electrical load is described. The system may include a processor that controls a signal generator to sweep across a frequency spectrum to locate a resonant frequency of the dynamic impedance load. The determination of resonant frequency may be made based on sensing the power consumption of the amplifier supplying the load and locating the frequency at which the power consumption is minimized. Periodically tracking and adjustment of the frequency to maintain a minimum power consumption may be automatically performed. The load may be a SAW atomizer.
