Abstract
A power supply, operating at line frequencies, for energizing a low-voltage lamp and like loads, utilizes a main capacitor in series with the load across the A.C. line source, and an auxiliary capacitor connected across the main capacitor by a switching device during a selected portion of the source waveform cycle. The minimum load current is established by the main capacitor, with additional load current flowing through the auxiliary capacitor during those portions of the source waveform cycle when connected, whereby the load current may be adjusted over a range established by the magnitude of the main and auxiliary capacitors. An open-loop circuit is disclosed for controlling the portion of the cycle during which the auxiliary capacitor is connected.
