Abstract :
This work presents the transient behaviour of paralleled 6.5 kV bipolar SiC diodes with aluminium implanted emitters. The switching behaviour at a current level of 30 A is shown at DC link voltages up to 4 kV and at a junction temperature of 125degC. Different IGBT gate resistor conditions realise different rates of current decay up to 1000 A/mus. Experimental results are discussed in terms of snappiness
