Abstract: 본 발명은 인버터의 성능을 테스트하는 장치에 관한 것으로, 종래에는 성능 시험을 하고자 하는 인버터에 저항부를 직접 부착하거나, 리액터 부하를 이용하여 시험하거나, 다른 부대 시설을 구비하여 실시하였다.
이러한 방법은, 매번 다른 부하 조건에서 시험이 수행되거나 현장에서 인버터가 개발되면, 시험을 수행하기 위한 기반 시설이 없기 때문에, 공급 전력이 부족하여 시험을 할 수 없는 경우가 발생하거나, 공급 전력이 충분하더라도 그 전력을 낭비하는 문제가 발생한다.
그뿐만이 아니라, 이러한 방법은 정격 전압에서 정격 전류를 제공할 수 없으며, 일정한 부하 전류 이외에는 성능 시험을 할 수 없는 문제점이 있다.
이에 본 발명은, 별도의 부대 시설이 필요 없이 인버터의 성능 정보인 파라미터와 사용하고자 하는 부하의 정보를 이용하여 성능 시험을 수행할 수 있는 시뮬레이션 장치를 이용하여 인버터의 성능 시험을 함으로써, 부대 시설을 간소화하여 경제적인 이점을 얻고, 그 성능 시험에 소모되는 노력을 제거하는 것이다.-

Abstract: PURPOSE: A variable power drive control system is provided to enable a railway vehicle to travel directly without exchange of a railway vehicle by corresponding elastically according to a railway system and a power supply manner of each nation. CONSTITUTION: A serial-to-parallel voltage converting circuit is connected to a variable power supply line. Four inverters are connected to form a serial circuit and a parallel circuit and invert a polarity of a power signal from the serial-to-parallel voltage converting circuit so as to supply current needed for a railway vehicle travel to electric motors. When a DC power of 3000V is supplied from the variable power supply line, the inverters whose regulated voltage of a DC link terminal is 750V, are connected in series by the serial-to-parallel voltage converting circuit, so that the DC power of 3000V is converted into a DC power of 1500V. When a DC power of 1500V is supplied from the variable power supply line, the inverters whose regulated voltage of a DC link terminal is 750V, are connected in parallel by the serial-to-parallel voltage converting circuit, so that the DC power of 3000V is converted into a DC power of 750V.
