Abstract
Typically, power factor is improved by adding a full power factor correction (PFC) stage between the rectifier and the power converter. This disclosure applies line voltage modulation to the control feedback of an isolated full bridge converter, thereby combining the PFC stage with the isolated power stage and forming a single state isolated power converter.
