The present invention relates to a railway car semiconductor transformer using a multi-winding high-frequency transformer. In the transformer, in order to convert AC power of a car line into DC power and output the DC power when the AC power is input, a plurality of input terminals of module converters having a multi-winding high-frequency transformer are connected to each other in series to receive a voltage of the AC power supplied from the car line, and a plurality of output terminals of the module converters are connected to each other in parallel to output power to a power bus. According to the present invention, simplification of a circuit supplying power to a traction load, an auxiliary load, and the like can reduce the weight of a railway car, thereby increasing energy efficiency and improving running performance and transportation capacity of the railway car.
본 발명은 다권선 고주파 변압기를 이용한 철도차량용 반도체 변압기에 관한 것으로; 전차선의 교류전원이 입력되면 직류전원으로 변환하여 출력하도록 다권선의 고주파 변압기가 구비되는 복수의 모듈 컨버터의 입력단이 서로 직렬 연결되어 전차선으로부터 공급되는 교류전원의 전압을 분담하여 입력받고, 상기 복수의 모듈 컨버터의 출력단은 서로 병렬 연결되어 전력을 분담하여 전원 모선으로 출력하는 것을 특징으로 한다. 본 발명에 따르면, 견인부하 및 보조부하 등에 전원을 공급하는 회로의 간소화를 통해 철도차량의 중량을 경감시킬 수 있어 에너지 효율 개선과 철도차량의 운행 성능 및 운송능력의 향상 효과가 있다.
