The voltage is rather low for IGBT's so the best answer is to look at FET
bridges. Try Seimens, Semikron, IXYS, Toshiba or IR all offer a range of
large FET's / IGBT's and drivers to interface to logic. With FET's watch the
RDSon as this can be the major power loss at these voltage levels. Is it
possable to increase the DC link voltage and hence decrease the current and
losses ?
