A new generation of intelligent power devices for motor drive applications

A new low loss, high speed series of intelligent IGBT power modules has been developed. Power device performance has been enhanced through the use of third generation IGBT chip technology with optimised gate drive and control circuits. Short circuit protection using current sense IGBTs with "real time" current limiting allows power devices to be optimised for lowest operational losses. Further reduction of losses is achieved through the use of a new ultrafast, soft recovery, free wheel diode chip. New compact isolated base packages containing six or seven power devices with current ratings up to 200 A at 600 V and 100 A at 1200 V are designed for cost effective, high performance motor control applications. This paper explains the internal design philosophy and architecture of these new devices.<>
