One-stage power factor correction (PFC) with output electrical isolation. Two types of PFC converters are proposed here: 1) Multi stage capacitive-switching network low voltage PFC converter and 2) two-switch soft switching PFC converters. This resulted in a near unity power factor AC-DC converter with...http://www.google.es/patents/US6594158?utm_source=gb-gplus-sharePatente US6594158 - AC/DC converter with power factor correction (PFC)
