Dear visitors of our web site!
In section "Information/Articles" "High Voltage Thyristors Adjusted for Usage in Series Assemblies and Stacks on Their Basis for Usage in Soft Starters of Electric Motors" article was added.
In spite of significant development of converters on the basis of fully controlled semiconductor stacks (IGBT, GTO, IGCT), today it's still technically legitimate and demandable to use "traditional" high power thyristors in stacks of controlled rectifiers as well as in soft starters of electric motors. Usage of thyristors is especially relevant in case of operating in AC network of 6/10 kV and higher, because the devices produced on the basis of such thyristors have no competition in price and energy efficiency (efficiency coefficient).
In the article there is a description of high voltage thyristors with relatively low reverse recovery charge, low temperature dependence, as well as high softness of reverse recovery.
