    Patent number: 8384361
    Abstract: An active phase angle correction circuit which corrects the phase angle between voltage and current in an AC supply varies the capacitive loading of the AC mains to reduce the phase angle to near zero by detecting the phase angle, reactively and resistively loading the AC mains in steps until the phase angle is at a desired level close to zero, and then maintaining or incrementally adjusting the loading. The applied loading may be continuously switched in and out at a rate much greater than the mains supply frequency.
