Under the heading FAQ (frequently asked questions), we provide answers to questions asked by our customers:

FAQs about CONCEPT

• Where is CONCEPT located?
  
  
• Is CONCEPT an independent company?

Questions on using and dimensioning drivers

• Can the gate charge specified in the data sheet of the power semiconductors be used to dimension the driver?
  
  
• Do CONCEPT drivers offer short-circuit protection for the IGBT/MOSFET module? Do CONCEPT drivers offer Vce /desaturation detection?
  
  
• Are CONCEPT drivers overload proof?
  
  
• Thermal measurements show that the temperature of certain driver parts exceeds 85°C. Is this permissible or is the driver thermally overloaded?
  
  
• Are short-term high-frequency bursts above the maximum switching frequency specified in the data sheet of plug-and-play drivers permissible?

Questions on circuit topologies

• Can CONCEPT drivers be used for direct series connection of IGBTs?
  
  
• Can CONCEPT drivers be used for multilevel converters?
  
  
• I use a CONCEPT driver core for a matrix converter (quasi-resonance converter etc). Why does the desaturation detector (short circuit protection) trigger regularly in the absence of a short circuit?
  

General Questions
