초록
Bilateral Variable-Ratio chopper system performs Step-down chopper and Step-up chopper operations automatically every operating period of the chopper. The Ratio between Step-down chopper and Step-up chopper operations is determined by a Tine- ratio and the circuit elements. In this paper, we suggest that this chopper system can operate variable speed control of the electric motorcar when it is applied to the electric motorcar.
