The present invention relates to a power converting device and a vehicle having the same. According to an embodiment of the present invention, the power converting device and the vehicle having the same comprise: a driving unit; a voltage detection unit detecting a voltage between a source terminal and a drain terminal of a switching element; a gate resistance variable unit varying a resistance value of a gate resistor connected to a gate terminal of the switching element based on the voltage detected from the voltage detection unit. Accordingly, a switching loss can be reduced while suppressing a surge voltage and a surge current caused by switching of the switching element.

    본 발명은 전력변환장치, 및 이를 구비하는 차량에 관한 것이다. 본 발명의 실시예에 따른 전력변환장치, 및 이를 구비하는 차량은, 구동부와, 스위칭 소자의 소스 단자와 드레인 단자 사이의 전압을 검출하는 전압 검출부와, 전압 검출부에서 검출된 전압에 기초하여, 스위칭 소자의 게이트 단자에 접속되는 게이트 저항의 저항값을 가변시키는 게이트 저항 가변부를 구비한다. 이에 따라, 스위칭 소자의 스위칭에 의한 서지 전압과 서지 전류를 억제하면서 스위칭 손실을 저감할 수 있게 된다.
