Power factor correction (PFC) circuit configured to control high pulse load current and inrush current

摘要

A power circuit for protecting against high pulse load current and inrush current is disclosed. The power circuit comprises a buck-boost module and a PFC controller operatively coupled with the buck-boost module. The PFC controller is configured to receive an input voltage feedback, an output voltage feedback, and a current feedback, and is configured to utilize one of an Integral Gain Compensation (IGC) and an Integral Value Compensation (IVC) to control the high pulse load current and inrush current in the power circuit.
