ABSTRACT:
A power match system for a train of individually powered traction vehicles in which two distinct types of power control systems are employed. The system includes a programmed power matched circuit which has programmed therein the volt-ampere characteristics of a motor operating under the control of one of the types of power control systems, such as a cam controlled resistor system. The power match circuit is serially inserted in the current command system for the other type of power control, such as a chopper controlled power system. A signal representative of the motor CEMF in the chopper system is supplied to the power match circuit which then regulates the current supplied by the chopper control power system in accordance with the programmed characteristics of the cam controlled resistor system. In this manner the motive power developed by the two distinct types of power control systems is matched whereby each type of system provides substantially the same pulling power to the train.
