Abstract
Embodiments pertain to a resonant power conversion system comprising switching circuitry configured to convert a low frequency AC power signal to a high frequency AC power signal, power conversion circuitry electrically connected in parallel with a source of the low frequency AC power signal and additionally connected in parallel with a consumer of the high frequency AC power signal. The source and the consumer may be electrically connected in series, and a low-pass filter may be serially connected between an output of the switching circuitry and the source of low frequency AC power signal.
