Purpose

• High voltage pulsed power applications
• Demonstration of a compact and modular design
• Repetitive 1 kHz burst operation

IGBT module, developed in cooperation
with ABB Switzerland Ltd.

IGBT module components

• Ø 155 mm double-sided pcb
• 15 IGBT dies with 1,7 kV (ABB 5SMX 12M1701)
• 15 gate drivers with active clamp circuits
• Ferrite core for inductively coupled
  triggering

High voltage (≤ 50 kV) testing stand
and modules under test in a Teflon
receptacle filled with an insulation liquid
(inset)

Results

 
Switching of 50 kV and 450 A with three IGBT modules in series connection
