Multilevel converter

A multi-level converter is disclosed. The multi-level converter comprises: an n^th sub-module; a (n+1)^th sub-module; and a ripple removing unit configured to remove ripple power by magnetically coupling the successive n^th sub-module and (n+1)^th sub-module connected to the same arm. The n^th sub-m...

More Information
Summary:A multi-level converter is disclosed. The multi-level converter comprises: an n^th sub-module; a (n+1)^th sub-module; and a ripple removing unit configured to remove ripple power by magnetically coupling the successive n^th sub-module and (n+1)^th sub-module connected to the same arm. The n^th sub-module and the (n+1)^th sub-module are connected in series and can output multi-level PWM voltages. 멀티 레벨 컨버터가 개시된다. 멀티 레벨 컨버터는, 제n 서브 모듈; 제(n+1) 서브 모듈; 및 동일한 암에 연결된 연속된 상기 제n 서브 모듈과 제(n+1) 서브 모듈을 자기적으로 결합하여 리플 전력을 제거하는 리플 제거부를 포함하되, 상기 제n 서브 모듈과 제(n+1) 서브 모듈은 직렬로 연결되며 멀티 레벨의 PWM 전압을 출력할 수 있다.
