Abstract

This paper proposes an advanced dead-time compensation method for dual inverter with a floating capacitor. The dual inverter with floating capacitor is composed of double two-level inverters and a bulk electrolytic capacitor. The output voltage of the dual inverter is dropped by the conduction voltage of the power semiconductors. The voltage drop and dead-time cause the fundamental and harmonic distortions of output currents. When supplied power for OEW-load is low, the dual inverter operates as single inverter for effective operation. The dead-time compensation method for the dual inverter operated as single inverter is needed for reliability. The proposed method using band pass filter in this paper compensates dead-time, dead-time error and changed voltage drop error of power semiconductors for the dual inverter and dual inverter operated as single inverter. The effectiveness of the proposed method is verified by simulation results.

본 논문은 플로팅 커패시터를 갖는 이중 인버터의 향상된 데드 타임 보상 기법을 제안한다. 플로팅 커패시터를 갖는 이중 인버터는 2-레벨 단일 인버터보다 전력 반도체가 6개가 추가된다. 전력 반도체의 수가 증가로 이중 인버터의 출력 전압은 추가된 전력 반도체의 도통 전압만큼 감소되며 출력 전류 품질은 전력 반도체에 의한 전압 강하와 데드 타임에 의해 저하된다. 본 논문에서 제안하는 기법은 이중 인버터의 데드 타임 및 전력 반도체의 도통 전압을 보상하여 전류 품질을 개선하고 추가적인 대역통과 필터를 이용한 고조파 보상 기법을 통해 데드 타임과 도통 전압 보상에 대한 오차를 추가 보상한다.
