A new generation of intelligent power devices for motor drive applications

A novel low-loss, high-speed series of intelligent IGBT (insulated-gate bipolar transistor) power modules has been developed. Power device performance has been enhanced through the use of third-generation IGBT chip technology with optimized gate drive and control circuits. Short-circuit protection using current-sense IGBTs with real-time current limiting allows power devices to be optimized 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. The internal design philosophy and architecture of these devices are explained.<>
