IPM(Intelligent Power Module),即智能功率模块,不仅把功率开关器件和驱动电路集成在一起,而且内部集成有过电压、过电流和过热等故障检测电路,内部含有高速低功耗的管芯和优化的门极驱动电路以及快速保护电路,即使发生负载事故或使用不当,也可以保证IPM自身不受损坏。IPM因其可靠性高,使用方便,特别适合于驱动电机的调速设计和各种逆变电源,但也有些事项需要注意。
IPM (Intelligent Power Module), that is, intelligent power module, not only integrates the power switching device and the driving circuit, but also integrates fault detection circuits such as over-voltage, over-current and over-temperature. It includes high-speed and low- Optimized gate drive and fast protection circuits ensure IPM itself is not damaged even in the event of a load accident or misuse. IPM because of its high reliability, easy to use, especially suitable for drive motor speed control design and a variety of inverter, but there are some matters needing attention.
