First Claim
Patent Images
1. A system for reducing distortion in an electrical signal having distortion comprising:
- a. an electric circuit for comparing at least a portion of the electrical signal having distortion in a power line to a desired reference signal, thereby forming a corrective signal; and
b. an electric circuit for selectively sinking and sourcing current to the electrical signal having distortion.

Abstract
Methods and apparatus for power factor correction include selectively coupling bit reactive loads with a load having dynamic reactive properties to dynamically correct a power factor. Methods and apparatus for reducing distortion in a power delivery system include a means for determining distortion in a power line, forming a corrective signal according to the distortion and selectively sinking and sourcing current to the power line according to the corrective signal.

10. An electrical circuit for reducing distortion in a current signal having distortion comprising:
-
a. a first input for receiving the current signal having distortion; b. a second input for receiving a reference signal; c. a substracter coupled to the first input and second input for comparing the current signal having distortion from the reference signal thereby a first corrective signal; and d. a circuit selectively sourcing and sinking current to and from the signal having distortion according to the corrective signal;
thereby reducing distortion in the signal having distortion. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
