ABSTRACT:
In a composite controlled semiconductor device having an insulated gate and a power conversion device using the same, a p type semiconductor region forming no channel is provided in the composite device structure between a plurality of p type semiconductor regions forming a channel and the potential of the p type semiconductor region in an ON state takes a value high enough to inject holes into an n type semiconductor region adjacent to the p type semiconductor region.
