The IGBT tube cores in the IPM are all high-speed type, and the driving circuit is close to the IGBT, so that the driving delay is small, and the IPM switch has high speed and small loss. The IPM is internally integrated with a real-time detection circuit capable of continuously detecting the current and the temperature of the IGBT, and when severe overload or even direct short circuit occurs and the temperature is overheated, the IGBT is controlled to be in soft turn-off, and meanwhile, a fault signal is sent out. In addition, the IPM also has the functions of bridge arm pair tube interlocking, drive power supply under-voltage protection and the like. Although IPM is expensive, IPM has advantages of compact structure, high reliability, easy use, etc. compared with a simple IGBT due to integrated driving and protection functions.
Some terminals used on the existing power module are directly plugged and pulled, and some terminals are fixed by bolts, so that the bolt type power module is troublesome to use, and the condition of poor contact is easily caused after the direct plugging type power module is used for multiple times.
