Abstract
A low loss capacitive delivery system for converting a low voltage AC power source into a driving energy for a high voltage lamp is disclosed. The system involves delivering two energy loops with the first energy loop consisting of a high voltage low energy output to the lamp during a first half cycle of the AC power source operation and the second energy loop utilizing a high energy low voltage system delivering a high energy capacitive pulse to the lamp during a subsequent second half cycle operation of the power source. The first energy loop functions to lower the resistance of the lamp and the second energy loop operates the lamp after its resistance has been lowered. The system contains a matrix of diodes arranged in order to deliver the capacitive pulse of the second energy loop and to bypass the low energy high voltage circuit.
