Abstract
Systems and methods are provided that may be implemented for overvoltage protection of bulk capacitors employed in power factor correction (PFC) circuitry components of switched mode power supply units (PSUs) using one or more inductive overvoltage feedback protection paths (OVPs) to monitor a voltage indicative of a PFC bulk capacitor by sensing the real time voltage at one or both of the primary and/or secondary side windings of a PSU transformer, and/or using an auxiliary windings of a PSU transformer.
