1. A power converter, comprising:
a power conversion circuit, electrically coupled between a first terminal and a second terminal, to convert a first voltage from the first terminal to a second voltage outputted at the second terminal; and
a protection circuit electrically coupled between an input terminal of the power converter and the first terminal, the protection circuit comprising:
a first protection device to withstand an input voltage of the power converter to continue an operation of the power conversion circuit when the input voltage exceeds a voltage threshold value; and
a clamping circuit electrically coupled to a control terminal of the first protection device to clamp a control voltage of the first protection device.
