전압제어 회로에 의한 호이스트용 통합 드라이브 장치 = The Integration Drive Equipment for Hoist by using Voltage Control Circuit

다국어 초록 (Multilingual Abstract)

An existent hoist drive system is using each different drive equipment in control of Hoisting, traveling(T/L), traversing(T/S) diving, so there, are much energy losses because of excessive weight. Also, power circuits are using relay contact, so working environment are frequent secession accident etc., by shock on unfavorable condition, and there is danger of safety accident, maintenance has frequent problem and so on. To solve these problem, it is integrated each driving power supply in drive system for hoist, control and drive, utility power supply etc., by single device in this research. The power circuit is consisted of non-contact circuit applying to bidirectional voltage controller circuit using thyristor that is power semiconductor switching device.
