Light - Weight, Compact, Power Electronics Converter System


Conventional power electronics converter (PEI) equipment is bulky, heavyweight, and requires regular maintenance, particularly because of the electrolytic capacitor that is used in such systems. These characteristics mean that the conventional PEI’s are not well suited for many applications where compactness, light weight and excellent reliability are required. In ship design, a compact lightweight PEI that can be located on the deck of the ship is desirable, in aircraft systems, a light weight PEI is always required. Oil and gas well drilling platforms offshore, floating offshore wind farms, and future undersea drilling stations would greatly benefit from the advantages of an improved PEI design.

A new PEI topology has been invented that features fewer passive components, with no electrolytic capacitor. The new design is compact and lightweight when compared to conventional systems. A further advantage is an increased fault current capacity such that the new design can withstand from 2 to 10 times the nominal current for 5 to 10 micro seconds without failure. These features of the new PEI make it ideal for many current applications as well as future applications where the advantages of the new PEI design will be absolutely necessary.
