Abstract
The present invention is a two unit electronic control system to reduce power demands imposed upon direct current power sources. The present invention comprises a contact/resistor network, a trigger generator, a pulse generator, a waveform stabilization circuit, a driver circuit, a voltage regulation circuit, a noise suppression circuit, a transient suppression circuit, a field effect transistor network and primary and secondary on/off control circuits. The input can be resistance, voltage, current or capacitance which is varied in response to an external stimulus. The chosen input is conditioned and applied to vary the duty cycle of a repeating pulse signal. That pulse signal is conditioned and applied to a switching device which controls the current from the DC power source to the load. The number of switching devices comprising the network will vary from one to many dependent upon the current carrying demand of the load and the current handling capability of the switching device utilized.
