ABSTRACT:
The firing loop of a SIR system has a firing element, a capacitor for passing AC pulses to the element and an inductance which varies according to application. A current sensor monitors each pulse and detects a threshold crossing on the trailing side of the pulse, and a toggle circuit operates a switch arrangement to terminate the pulse and initiate the next pulse of opposite polarity. This current feedback circuit varies the pulse frequency according to the loop inductance but the RMS loop current is independent of inductance.
