Abstract
A boost converter circuit and method of operating the same is provided. The boost converter circuit includes a bridge rectifier configured to convert an alternating current (AC) voltage at a rectifier input to a rectified voltage at a rectifier output; a transistor switch coupled between the bridge rectifier and a DC link capacitor, and configured to receive a control signal in order to regulate a charging and a discharging of the DC link capacitor; a surge voltage detection circuit coupled to the rectifier output, and configured to measure the rectified voltage for detecting a surge event based on the measured rectified voltage; and a gate controller configured to output the control signal to the transistor switch, wherein, upon occurrence of the surge event, the gate controller is configured to turn off the transistor switch for a predetermined delay period via the control signal.
