A 10 kw Lightweight DC Converter (Technology Feasibility Study for Lightweight Megawatt Range Converters).

reportActive / Technical Report | Accession Number: ADA049937 | Open PDF

Abstract:

The technology for an ultra-reliable, lightweight, high power dc converter is presented and supported by test data of a small 10 kW feasibility model. Reliability and a high efficiency near 97 percent are derived from a process of natural current commuration of fast switching thyristors in series resonant circuits. Lightweight is the result of an internal frequency near 10 kHz. The feasibility of 150 kW single modules with one set of thyristors is indicated. The salient features of this converter technology are highlighted. Author
