Abstract
A surge suppressor is connected in parallel to a circuit breaker of an input path of a MVAC conversion circuit. The surge suppressor includes a plurality of surge suppression circuits, and each surge suppression circuit includes a rectification circuit, a switch, a controller, and a conversion circuit. The rectification circuit includes an AC terminal and a rectification terminal, and the AC terminals of the surge suppression circuits are coupled in series. The switch is coupled to the rectifier terminal, the controller receives a control command and provides a control signal according to the control command. The conversion circuit is coupled to the controller and the switch, and provides a control voltage modulated by the control signal. The control voltage adjusts an on-resistance of the switch to adjust a magnitude of a first current flowing through the switch.
