为满足用户高性能、多功能、高可靠性等方面的要求,三菱电机公司开发出新型功率智能模块(IPM)。这种功率模块将输出功率元件与驱动回路集成在一起,有防止过电流和过热的功率回路保护、负载侧故障保护以及误操作保护功能等。模块的输出元件使用了IGBT,设有电流监控用传感器端子,并且,内藏带电流传感器的功率回路。由于功率回路、驱动回路及保护功能均实现了集成化,使以往单功能的单一元件变 In order to meet user’s high-performance, multi-functional, high reliability and other requirements, Mitsubishi Electric Corporation developed a new type of power intelligent module (IPM). This power module integrates the output power components with the drive circuitry, power loop protection against overcurrent and overheating, load side fault protection, and misoperation protection. IGBTs are used as the output elements of the module, and sensor terminals for current monitoring are provided, and power circuits with current sensors are built-in. As the power circuit, drive circuit and protection functions have been integrated, so that the past single-function single-element change
