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.
Claims27
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 including a plurality of selectable loads for selectively sinking and sourcing current to the electrical signal having distortion.
An electrical circuit for reducing distortion in a current signal having distortion in a power line, the electrical circuit comprising:
- a. a first input for receiving the current signal having distortion;
- b. a second input for receiving a reference signal;
- c. a subtractor coupled to the first input and second input for subtracting the current signal having distortion from the reference signal thereby forming a corrective signal;
- and
- d. a circuit for selectively sinking and sourcing current from and to the current signal having distortion according to the corrective signal, the circuit comprising a plurality of selectable loads;
- thereby reducing distortion in the current signal having distortion.
