High Voltage Power Semiconductor Modules with Enhanced Insulation Properties


One of the main parameters related to reliability and safety of power semiconductor modules is the strength of electric insulation. Breakdown of the electric insulation not only causes failure of the module, but also damages the entire converter leading to high financial losses. This article discusses the current situation on the market of bipolar power modules, the importance of improving their insulation properties and stability of insulating properties throughout the entire life cycle. The Proton-Electrotex company has carried out research and development to find structural and technological solutions providing increased insulation strength up to 7 kV (AC) throughout the entire service life.
