Scholarcy highlights

  • In the field of High Voltage Power Conversion, the circuit designer is often confromed to a serious problem: there arc no semiconductors capable of sustaining the desired voltage
  • The output dV/dt at each commumtion is the sum of the dV/dt genceratd by each switch, which is a serious stress for the environment and especially the firing circuits! The technique presented in this paper tolerates semiconductors switching at different times, allowing high voltage conversion with standard dV/dr
  • His research interests include soft commutated power supplies, power devices modelling for converter simulation, and high voltngc/high frequency conversion
  • Easy remote access to your institution's subscriptions on any device, from any location
