1. An integrated power quality control system, comprising:
- a transformer including a primary winding, at least one secondary winding and at least one compensation winding wound on a magnetic core;
a power electronic converter providing a reference voltage to the compensation winding for injecting a series voltage in the at least one secondary winding; and
a controller to generate a reference control voltage for the power electronic converter based on a power quality control requirement;
wherein the controller generates the reference control voltage based on a relationship between a turns ratio of the at least one compensation winding and the secondary winding, and a reference secondary winding voltage determined based on the power quality control requirement.

Abstract
An integrated power quality control system includes a transformer with a primary winding, a secondary winding and a compensation winding wound on a magnetic core. A power electronic converter in the system provides a reference voltage to the compensation winding for injecting a series voltage in the secondary winding of the transformer. A controller is utilized to generate a reference control voltage for the power electronic converter based on a power quality control requirement.

14. A method of controlling power to a load, comprising:
-
providing a transformer including a primary winding, at least one secondary winding and at least one compensation winding wound on a magnetic core; generating a reference control voltage for a power electronic converter based on a power quality control requirement; and utilizing the power electronic converter to provide a reference voltage across the compensation winding for injecting a series voltage in the at least one secondary winding; wherein the reference control voltage is generated based on a relationship between a turns ratio of the at least one compensation winding and the at least one secondary winding, and a reference secondary winding voltage determined based on the power quality control requirement. - View Dependent Claims (15, 16, 17, 18, 19)
