Title: Chopper controller of electric rolling stock
Inventor: YOMO SUSUMU
IPC: H02P3/14
Filed: 1979-06-26
Abstract: PURPOSE:To prevent a main circuit from being opened due to excessive reduction under light load, by performing optimal reduction at optimal timing when short- circuiting a resistor. CONSTITUTION:A timer circuit 26 acts synchronously with the output of a resistor short-circuit condition detecting circuit 21 to supply an output after a prescribed time. The output of a current detection circuit 14 is supplied to a current reduction circuit 23 to apply a quantity of reduction proportional to a braking current. Even if an aerial conductor voltage limiter 20 is acting and the current of a motor is reduced below a braking current pattern, the current reduction quantity at the time of short-circuiting of a resistor 10 is proportional to the current actually flowing through the motor. This results in preventing a drawback such that a current relay drops off due to an excessive reduction quantity.
