Abstract:
A nonlinear, active network that transforms the voltage waveform of a unipolar source of energy is presented. This network consists of ideally lossless elements such as inductors, capacitors, and on-off switches. Control is obtained by variation of the mode of switch operation. A circuit philosophy is applied which is adapted to the characteristics of switch operation and confines the stresses imposed on circuit components to moderate levels. Results of experimental work are reported and include: 1) test data of a 95 percent efficient, 2-kW dc transformer having a power density of 0.4 kW/kg; and 2) integration of this transformer with a 20-cm ion propulsion engine for spacecraft.
