Abstract

See full text

An instantly variable constant current control is interposed between a bank of batteries and a motor. The variable constant current control comprises a series pass transistor operating in a linear mode and controlled by a reference voltage from a potentiometer coupled to an accelerator pedal. Correction voltage from the series pass transistor circuit is proportional to current. The accelerator reference voltage and the current correction voltage are compared in a linear operational amplifier which controls the 'on' resistance of the series pass transistor.
