RTGC의 연료절감을 위한 전압 보상 컨버터에 관한 연구

This paper presents a development of voltage compensation dc/dc converter to decrease fuel consumption of RTGC system. We used 3-phase interleaved converter, which has the same structure as the commercially available three-phase inverter, is used. RTGC system is supplied the power from diesel-engine generator. According to power demand, engine speed is varying 20~60㎐, and voltage is varying 210Vac ~ 480Vac. When idle mode or low power operation dc/dc converter operates by constant output voltage control. The perpormance of converter is evaluated through several experiments with a real RTGC. Proposed system can cut down fuel consumption by 36% at idle mode operation.
