Abstract
A power supply providing power to a low voltage lamp utilizing a main capacitor connected electrically in series with the lamp, across an alternating current source, and an auxiliary capacitor connected electrically across the main capacitor by a switching device during selected portions of the source waveform cycle. The minimum lamp current is established by the main capacitor, with additional lamp current flowing through the auxiliary capacitor during portions of the source waveform cycle when the auxiliary capacitor is electrically connected across the main capacitor. The load current is adjusted over a desired range established by the magnitude of the main and auxiliary capacitors.
