摘要 |
In an electrically driven vehicle which is controlled by a thyristor chopper circuit having a main thyristor in series with the traction motor and a commutating thyristor for turning the main thyristor off, demand means is provided for setting a required current through the motor and firing the commutating thyristor when the required current is attained. An overriding control permits firing of the commutating thyristor when the main thyristor has been on for a predetermined period, and timing means operates when the overriding control is operative for setting the minimum off period of the main thyristor. |
