Abstract
A resonant AC-to-DC converter apparatus includes an inductance circuit comprising an inductor with a first and connected in series with each phase of an AC power source comprising a fundamental frequency, and a capacitance circuit that includes a capacitance for each phase. Each capacitance is connected between a second end of the inductor of a phase and a neutral connection, and the capacitance and the inductor of the connected phase form a resonant frequency. The apparatus includes a rectification circuit with an input and an output, the input connected, for each phase, in series with the second end of the inductor of the phase. The resonant frequency is related to the fundamental frequency to provide a gain at the fundamental frequency, the gain boosting a voltage of the input to the rectification circuit at the fundamental frequency above an output voltage of the AC source.
