Solution for Power Module industry

New SiC switching technology bring significant advantages to Power Electronic Industry. It opens up a very broad range of possible improvement: compact designs, system power density increase, etc. but it’s also a challenge for electric interconnect systems which have to “follow the trend”. 

New development are pushing research for new inductance minimization methods (especially for MV and HV modules).

Evolving Insulation system challenges

  • Higher switching frequency (from Si IGBT to SiC MOSFET)
    • 10/20kHz…. 50kHz…. 200kHz
  • Higher temperatures
    • SiC chips can operate at a much higher temperature
    • Some specific applications already require 200°C busbars
  • Higher voltages
    • Additional stress on insulation systems (especially low inductive types)
    • Partial discharge
  • Long product life cycle expectations
    • New systems = 30y lifetime
  • System compactness
