Title: DC to DC Voltage converter

Abstract: A DC voltage source of amplitude below the DC voltage requirement of a load to be energized drives a pair of complementary transistors which are alternately turned on and off to apply supply voltage alternately to each of two capacitors connected in series. The sum voltage of the two capacitors is applied, in one embodiment, directly to a voltage regulator and filtered and, in another embodiment, is added to the DC source voltage prior to being regulated and filtered. The converter output is capacitively coupled to the DC supply voltage, thus furnishing a common AC connection.
