Zusammenfassung:	Suggested is a modular multilevel converter for HVDC to supply power to a plurality of sub circuits included in the modular multilevel converter with one power source by serially configuring a bootstrap. The suggested modular multilevel converter for HVDC includes: a plurality of sub modules which are configured by the combination of a switching element and a capacitor; a plurality of gate drivers which control the switching of switching elements of the plurality of sub modules; and the bootstrap which supplies the power to the plurality of gate drivers through one voltage source. 부트스트랩을 직렬로 구성해 하나의 전원으로 모듈형 멀티레벨 컨버터에 포함된 복수의 서브 회로에 전원을 공급하도록 한 HVDC용 모듈형 멀티레벨 컨버터를 제시한다. 제시된 HVDC용 모듈형 멀티레벨 컨버터는 스위칭 소자 및 커패시터의 조합으로 구성되는 복수의 서브모듈; 복수의 서브 모듈의 스위칭 소자 개폐를 제어하는 복수의 게이트 드라이버; 및 하나의 전압원을 통해 복수의 게이트 드라이버에 전원을 공급하는 부트스트랩을 포함한다.
