CORPE – in operation
Equipment for CORPE – located special areas
• Characterization of power semiconductor devices (low voltage, medium
voltage) – switching losses
• Termographical equipment (Flir)
• CALT system
• Double thermal chamber system for stressor loading
• Power cycling systems for power modules, capacitors (many and in
collaboration with companies)
• SIMS (Nano-department)
• More to come
Software-tools
• Reliasoft
• Ansys
• Sherlock
• PLECS, Saber etc
