Abstract
A power supply system and related method for providing a regulated DC output from an unregulated AC input includes a Vienna rectifier having power factor correction circuitry and a series resonant DC to DC converter to provide a regulated DC output. The power supply system further includes one or more compensator circuits coupled in feedback configuration to control the Vienna rectifier and/or the DC to DC converter and avoid a potentially dangerous over-voltage condition at the regulated DC output.
