Advance high power semiconductors devices in drives and power conversion

Abstract

This Paper focuses on Westcode Semiconductors' advanced high power devices; Diodes, Thyristors and Press-Pack IGBTs.Westcode, a division of IXYS Corporation, manufacture devices for use on many power sub-assemblies and have been meeting the strenuous demands of various applications within traction and energy markets. Electrical system performance is calculated using conventional methodology together with a computer thermal model. This modelling program uses an iterative approach to optimise various aspects of the design. The calculation, design, testing and operation of these power sub-systems are also presented and validated by experimental results.

Press pack IGBT: high current pulse switch transcranial magnetic simulation

“…Semiconductor switches have been available for many years serving the highest end of the power market with press-pack IGBT technology used in various applications [1] including pulse power conversion [2,3 &4]. Repetitive transcranial magnetic stimulation (rTMS) is a wellestablished neuro-modulatory approach with a range of applications such as treatment of psychiatric and neurological disorders among others.…”
