Abstract
Abstract A load is connected across one DC source of a first polarity and is connected to the opposite polarity of a second DC source, the two sources being connected in series with a capacitor/resistor network, or other voltage maintaining circuit, connected in parallel with the series combination of the two sources. The first source drives the load in one polarity and the second source drives the load in the other polarity thereby to achieve rapid slewing of the voltage across the load. In another embodiment a fixed power source may be connected in series with the first power source so that the slewing of voltage across the load occurs above a given reference level. The first and second sources are driven in a complementary fashion so that the sum of their instantaneous output voltages is always constant and equal to the individual maximum voltage which each may obtain. Since the slewed sources comprise a high voltage bilateral system, feedback may be utilized for stability and accuracy.
