Abstract
The present disclosure relates to a power converter capable of improving stabilization while minimizing loss when switching a switch included in the power converter. The power converter includes a switch; a gate driver configured to drive the switch at a predetermined duty ratio and apply a positive voltage when the switch is turned on and a negative voltage when the switch is turned off; a negative power supply unit configured to supply the negative voltage to the gate driver and vary a magnitude of the negative voltage; a current sensor configured to sense a current flowing in the switch; and a control unit configured to control the negative power supply unit to adjust the magnitude of the negative voltage applied to the switch according to a value sensed by the current sensor.
