Abstract
A power generator system and apparatus that uses a frequency synthesizer in conjunction with an oscillator to lock both frequency of a drive signal with a reference signal. The oscillator center frequency is different from the nominal generator frequency, and as a consequence a variety of reference frequencies may be supported. By using a frequency synthesizer, the oscillator frequency can be locked onto a frequency that is a ratio of the reference frequency. Then, the frequency synthesizer may generate a drive signal that is closely matched to the reference frequency.
