Advance high power semiconductors devices in drives and power conversion

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. (4 pages)
