ABSTRACT:
A PWM controller for an electrical utilizes a dual differential input topology comprising two input comparators deriving a proportional reference from two potentiometers for providing a variable pulse width modulated output. The pulse width modulation controller of the present invention does not require scaling and may be utilized in appliances, robotics, toys and in conjunction with other electromechanical and electrical loads.
