ABSTRACT:
A plurality of SCR diamond bridge circuits are coupled in series to generate frequencies higher than the individual operating frequencies of the SCR's. The series chain of diamond circuits is preferably coupled in parallel with the series combination of a DC blocking capacitor and an inductive load. The chain is provided with current from a substantially ripple-free constant current source, and the firing times of individual SCR's can be controlled to minimize the di/dt in each SCR.
