TLDR
In this article, the authors describe the development and implementation of gate drive ICs that rely exclusively on external coreless transformers (ECT) for both signal and continuous power transfer.Abstract:
This paper describes development and implementation of gate drive ICs that rely exclusively on external coreless transformers. Both, signal and continuous power are transferred via coreless transformers. The newly developed "double pulse" signal transmission scheme facilitates save switching under voltage transients higher than 95 V/ns. Reliability of the planar insulation on the printed circuit board is found to be as good as for conventional ring core molding, or better. Dedicated layer buildup and material selection prevents insulation failure due to formation of conductive anodic filaments.read more
