Abstract
The invented voltage regulator is a solid state low voltage regulator for in-line power lines for LED arrays and incandescent lamps, preferably low-voltage halogen lamps. The invented voltage regulator comprises, in combination, a full-wave bridge rectifier circuit, a voltage sensing circuit across the output of the full wave bridge rectifier circuit, and an AC power line voltage control circuit across the output of the voltage sensing circuit, the output of the AC power line voltage control circuit controlled by a switching power control circuit to provide a regulated 11.0 to 12.5 V AC output regardless of line voltage variations.
