Technology Marketing Summary

As the use of renewable energy sources increase, there is an increasing need for power converters capable of efficiently converting a diverse input of energy sources to a form suitable for insertion into modern electrical grid systems.  Current renewable energy conversion systems are bulky, inefficient, and generally incapable of efficiently accepting multiple inputs from a diverse pool of energy sources, such as produced by modern, renewable photovoltaic, geothermal and wind energy systems.  

Description

Researchers at the University of Arkansas have invented a novel power converter using a high-frequency matrix converter, which provides a simplified control system allowing for a small transformer to simultaneously accept power from a variety of sources and produce stable electricity ready to be inserted into the electrical grid system.  DOE has been granted U.S. Patent 8,995,159 on the technology and is seeking licensing opportunities for this innovation.

High-frequency matrix converter with square wave input
A device for producing an alternating current output voltage from a high-frequency, square-wave input voltage comprising, high-frequency, square-wave input a matrix converter and a control system. The matrix converter comprises a plurality of electrical switches. The high-frequency input and the matrix converter are electrically connected to each other. The control system is connected to each switch of the matrix converter. The control system is electrically connected to the input of the matrix converter. The control system is configured to operate each electrical switch of the matrix converter converting a high-frequency, square-wave input voltage across the first input port of the matrix converter and the second input port of the matrix converter to an alternating current output voltage at the output of the matrix converter.
