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.

A power supply system for providing a regulated DC output from an AC input comprising:
- a rectifier for converting said AC input into a rectified DC output,
- a DC to DC converter coupled to said rectifier for providing a regulated DC output,
- a first compensator circuit coupled to monitor the output of said DC to DC converter,
- a second compensator circuit coupled to monitor the output of the rectifier, said first and second compensator circuits each coupled to provide feedback control of said rectifier to prevent an over-voltage at the regulated DC output.
