TDK-Lambda to examine rectifier loss reduction in a paper at PEMD 2010

The paper will disclose some of the most recent developments in this field, and reports on practical techniques that will allow the production of power supplies that are more efficient than their present-day counterparts.

The paper is scheduled for presentation on the first day of this prestigious conference, which is taking place between 19th and 21st April at the Thistle Hotel in Brighton. The paper’s authors are Andrew Skinner, Chief Technology Officer, TDK-Lambda UK Limited, and Christopher Bennett, Electrical and Electronics Design Engineer at TDK-Lambda UK Limited.

“Resonant converters are becoming very popular in off-line applications where high efficiency is a key consideration,” said Andrew Skinner, “so TDK-Lambda has done a lot of work on optimising efficiency with converters of this type.”

“The results to date are presented in this paper, which looks at the performance improvements we’ve been able to achieve using an LCC topology with full-bridge synchronous rectification, compared to TDK-Lambda’s patented NV topology, which is an LLCC technology. The paper also presents a novel low cost scheme for driving synchronous rectifiers more efficiently.”
