Abstract

The current peak through an inductor is controlled more accurately and becomes independent from the pedestal voltage. External timing for the pedestal pulse width is eliminated. A conventional pedestal driver delivers a high voltage pedestal for a fixed period of time, then decreases to a level which will sustain the current. See Figs. 1 and 2. The current through the inductor L is described by equations 1-3. See Original.
