Today’s communications demand state of the art, efficient and compact DC power systems. Unity Power Systems deliver an industry leading power density, efficiency and superb reliability at lowest lifetime …

Increasing network speed demands flexible and expandable DC power solutions. The Flatpack2 rectifiers combined with Smartpack S controller are your key building blocks for future needs.

In this paper, after some brief recalls on the passive PF correction technique, a new electrical scheme for thyristor based controlled single-phase rectifiers is firstly introduced, in order to make possible the …

hardwire 208/240V input power (output de-rates to 4800W at 208V with included L6-30P cord option). In double-conversion mode, this UPS system maintains perfect output by continuously converting AC …

For instance, if a customer is exporting to the grid, the power factor wants to be as close to unity as possible, as the electricity companies pay for the kW’s supplied.

Abstract -- A new 3-phase buck-boost unity power factor rectifier consisting of a 3-phase bridge buck PFC rectifier and two boost dc-dc converters connected in series is proposed for an industrial …

In these applications, converters can provide input currents without distortion and with the unity power factor. In this paper, a unified discrete event model is given for power electronic circuits, based on a …
