摘要

目前，在铁路牵引中，为了减轻输入变压器的重量和体积，几种采用中、中频级的结构正在研究之中。主要的问题是用高压器件达到高的开关频率。本文提出了一种基于对偶结构关联的软交换拓扑。计算了软换相模式下6.5 kV igbt的开关损耗。

Medium frequency transformer for railway traction: Soft switching converter with high voltage semi-conductors

Nowadays, in railway traction, in order to reduce the weight and the size of the input transformer, several structures using intermediate medium frequency stages are under consideration. The major problem is to reach a high switching frequency with high voltage devices. In this paper, the authors propose a soft commutated topology based on dual structure association. The switching losses are calculated considering 6.5 kV IGBTs in soft commutation mode.
