Abstract

Systems and methods are disclosed that operate to correct the electrical characteristics of an electric distribution system based on analysis at a particular point in the system, for example, at a customer's meter. To do so, the subject characteristic may be measured at the meter. The subject characteristic may be provided to a power inverter controller, which responds by modifying the characteristic of the inverter output to achieve the desired measurement at the meter.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of priority to International Application No. PCT / US2016 / 024974, entitled “SYSTEMS AND METHODS FOR SHUNT POWER FACTOR CORRECTION”, filed Mar. 30, 2016, which claims priority to U.S. Provisional Application No. 62 / 140,725, entitled “SYSTEMS AND METHODS FOR SHUNT POWER FACTOR CORRECTION”, filed on Mar. 31, 2015, which claims priority to U.S. Provisional Application No. 62 / 047,443, entitled “SYNCHRONOUS BUCK INVERTER,” filed on Sep. 8, 2014, all of which are incorporated herein by reference as if set forth in their entireties.FIELD OF THE DISCLOSURE

[0002] The present disclosure relates to power conversion, and more particularly to ensuring the connection of a load to an electric utility grid has an alternating current (AC) waveform at a desired (e.g., unity) power factor, regardless of the power factor of the load, and regardless of the power factor of the grid. The AC waveform may be generated by an inverte...
