Abstract
An electrical control circuit particularly adapted for providing high current pulses in a wide frequency pulse range. The circuit is comprised of a timing and control circuit, a high power switching circuit, and an interfacing isolating circuit. The timing and control circuit includes a plurality of variable frequency pulse generators whose outputs are distinguished and combined to form a single wave signal. The power switching circuit includes a plurality of high speed switches for applying high current pulses to a load in associated response to the wave signal. The isolating circuit includes a plurality of isolating switches for insulating the timing and control circuit from interference from the power switching circuit while permitting the timing and control circuit output to control the application of higher energy and frequency pulses by the power switching circuit to a load than was heretofore available.
