CPC classification number: H02M7/217 , H02M3/158 , H02M3/28 , H02M2001/123 , Y02B70/1425 , Y02B70/1441
Abstract: 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.
