Serial connected active voltage clamping


The new post project for uranium enrichment SILVA needs specific power converters. The LETC laboratory of the C.E.A. in Pierrelatte has been studying these since 5 years. The aim of this laboratory consists in developing high voltage solid-state converters using a large number of small standard solidstate components (MOSFETs, IGBTs, thyristors and diodes) connected in series. In these associations, voltage balancement system are not used, but the voltage is limited on each stage in its safety area by clamping protection. This paper describes different voltage clamping systems, active clamping technique and their association in series.
