Publication number: 20170117819Abstract: A method and device for providing isolated power transfer to a low-power load across a capacitor of a series resonance circuit are shown. The method includes comparing an output voltage received via a feedback loop with a desired output voltage. Responsive to determining that the output voltage is not equal to the desired output voltage, the method determines a sub-harmonic order of the resonant frequency of the series resonance circuit to use as a switching frequency and switches the series resonance circuit at substantially the determined subharmonic order of the resonant frequency.Type: ApplicationFiled: December 7, 2015Publication date: April 27, 2017Inventors: Lei Chen, Rajarshi Mukhopadhyay, Mark W. Morgan, Joseph A. Sankman
