Recitiverter can replace a UPS

The Rectiverter combines rectifier, inverter and transfer switch in a box

 Eltek in Norway launches the Rectiverter, a power conversion box combining the functions of a rectifier, an inverter and a “static transfer switch”. The Rectiverter is a 3-port bidirectional converter that simplifies solutions providing both AC and DC power to critical loads in telecom, data center and industrial applications. It features a power conversion efficiency of 96% in mains mode and 94% when operating as an inverter. First product is the Rectiverter HE, delivering 230 V/1500 W AC and 48 V/1200 W DC. It features high power conversion efficiency, and is controlled by a single controller. Rectiverter systems are available as single or 3 phase, input and output, and can be scaled to meet any power demand.

 The Rectiverter combines the functions of a rectifier and an inverter, and eliminates the need for a static transfer switch. The Rectiverter has three ports - one AC input, one AC output and one bidirectional DC port for both input and output.  During normal operation, the Rectiverter provides both AC and DC power with a total load of up to 2000 W per cabinet.  The AC input is first rectified, then fed to a built-in inverter for AC output. The rectified AC input is fed to a DC/DC converter for appropriate DC load output, and to batteries for charging. In case of AC (mains) failure, the DC flow is reversed from the batteries to feed the inverter for conversion to AC, and to take over the DC load. The transition from AC to DC feed is instantaneous and with no load disturbance.  The Rectiverter is a combined AC UPS and DC power supply, but can also be used as a pure inverter. “To integrate a rectifier and an Inverter in the same box, with bidirectional power flow and still maintain high efficiency is an impressive achievement,” commented Dr. Tore M. Undeland, Prof Emeritus of Electrical Engineering at Norwegian University of Science and Technology (NTNU).
