Current-Modulated Smart Distribution Transformers, Modules, Systems, and Methods

摘要

A smart transformer comprises a current-modulated electronic power converter with an Alternating Current input (AC Port 1), an Alternating Current output (AC Port 2) and an optional Direct Current input/output (DC Port). A control mechanism allows the converter to provide full AC-AC conversion, changing AC voltage, phase, and power between the two AC ports, with the balance of the power supplied or delivered to the DC port that is connected to an energy storage device.

主权项

1. A method of operating a power distribution system, comprising the actions of:
in a primary distribution station, using a transformer to step down the voltage of power received from transmission lines, to thereby provide power at a primary distribution voltage on primary distribution lines; in a power-packet-switching converter module, reducing the voltage of power received from said primary distribution lines, to thereby provide a power supply to one or more customers, at a reduced secondary distribution voltage; while also minimizing variation of the secondary distribution voltage, using dynamic response of said converter module.
