PhD work
Focus is on using dielectric fluid as combined insulation and cooling medium for the power electronic devices.
  • The dielectric fluid is exposed to the high electric fields at the surface of the semi-conductor devices.
  • The main topic of the PhD study is on field distribution close to the semi-conductors and on discharge and breakdown phenomena in the dielectric fluid.
  • he field close to the semi-conductor is inhomogeneous, the field strength is very high with small gap distances and both dc and high frequency components are present.
  • The candidate is working on studying discharge phenomena in the dielectric fluid under these conditions.
