Beschreibung
Zusammenfassung:	The present invention relates to an inverter control method for railway vehicle air conditioners, capable of preventing overcurrent from being applied to a compressor motor attached to an air conditioner of a railway vehicle or a step-out phenomenon, and controlling an output voltage and a frequency of an inverter that supplies power to the compressor motor by accelerating each section according to a rotational speed of the compressor motor. The inverter control method for railway vehicle air conditioners comprises: a speed command input step; an acceleration control step; a deceleration control step; a maintenance control step; and a return step. 본 발명은 철도차량 공조기에 부설된 압축기모터에 과전류가 인가되거나 탈조현상을 방지토록 상기 압축기모터에 전력을 공급하는 인버터의 출력전압과 주파수를 상기 압축기모터의 회전속도에 따른 구간별로 가속하여 제어하는 철도차량 공조기용 인버터 제어방법에 관한 것이다.
