Abstract

The current invention consist of a Phase conversion device with built-in demand reduction/power boosting device where Single phase AC is converted to DC and connected to a DC storage device, which again is connected to a DC to three phase AC converter and where a single phase AC is feed into a current limiting device and then into a single phase to three phase AC converter. A DC storage device with a DC to single phase AC converter is connected between the current limiting device and the AC to AC phase converter.

Claims
