ABSTRACT:
A family of consolidated soft-switching AC/DC PFC converters, for power supplies and related uses. Any of several effective circuitry designs is interposed from an intermediate node on a rectified positive lead to a preselected intermediate node operative as a high-frequency AC source in a DC/DC conversion stage. Features so optimizable, individually or in combination, include power factor, regulation, and efficiency, plus reduction in circuit complexity.
