Abstract
A three-phase alternating current (AC) to direct current (DC) power converter includes a boost power factor correction (PFC) circuit that includes a low frequency diode-based converter, and a PFC inductor and a PFC capacitor connected in series together and in parallel to a PFC output of the converter. The boost PFC circuit further includes either a high frequency PFC diode and a high frequency PFC switch or a plurality of high frequency PFC switches. A Ćuk converter includes a first Ćuk inductor and a Ćuk capacitor, a second Ćuk inductor and a high frequency Ćuk diode, and a transformer having a primary side connected in parallel to the PFC capacitor and a secondary side connected in parallel to the Ćuk capacitor.
