Abstract :
In high voltage applications of inverters, series connection of power semiconductors is a well known solution. This paper presents a progressive driver/snubber scheme producing its own supply voltage without external power supply. Besides that, voltage distribution and snubber behavior are optimized and snubber energy is regenerated to the DC link of the inverter. Measuring results obtained from a real IGCT-inverter are presented
