ABSTRACT:
An improved drive circuit for steering a motorized wheelchair. A control mechanism produces right and left drive signals to respective right and left wheel drive motors. These right and left drive signals are amplified by right and left amplifiers to provide the necessary magnitude power signal to the motors. The input to the amplifiers are cross-coupled so that each amplifier will amplify its own input signal plus a portion of the cross-coupled input signal.
