This paper presents a novel method of power-factor correction (PFC) using a high-frequency resonant energy tank for the dc-link inverter. The proposed approach has advantages over conventional PFC techniques in terms of a lower current stress and lower switching losses. The developed PFC circuit is implemented on a series-load resonant inverter for illustrative purposes. The experimental results validate the theoretical analyses. The PFC circuit can achieve a power factor of almost one with a very low harmonic distortion.
