A new design of the SCR type speed controller for the battery powered electric vehicles

SCR을 이용한 전기자동차의 속도제어장치의 설계와 시작

A new design method for the SCR-Chopper type speed controller of the battery-powered vehicles was developed. The conventional speed-controllers were either inductance type or contact type using resistance. In the new method, a photocoupler was used in sensing the control currents and a noncontacting type photo-conductive device (CDS) was used in mading acceleration. Experiments using these new devices showed encouraging results.
