Power Test and Technical Research Report Analysis of IPM Module of Variable Frequency Air Conditioner

变频空调控制器核心器件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。而且其内部还集成有过电压,过电流和过热等故障检测电路,并可将检测信号送到CPU。它由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构成。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一般使用IGBT作为功率开关元件,内部集成电流传感器及驱动电路的集成结构。IPM以其高可靠性,使用方便赢得越来越大的市场,尤其适合于驱动电机的变频器和各种逆变电源,是变频调速,冶金机械,电力牵引,伺服驱动,变频家电的一种非常理想的电力电子器件,应用层面对其功率测试与技术研究报告分析。

IPM(Intelligent Power Module), the core device of variable frequency air conditioning controller, not only integrates power switch devices and drive circuits together. In addition, it also integrates fault detection circuits such as overvoltage, overcurrent and overheating, and can send detection signals to the CPU. It consists of a high-speed lowpower die, an optimized gate drive circuit and a fast protection circuit. Even in case of load accident or improper use, the IPM itself can be protected from damage. IPM generally uses IGBT as the power switching element, and the integrated structure of the internal integrated current sensor and drive circuit. IPM, with its high reliability and ease of use, has won a growing market. It is especially suitable for frequency converters and various inverter power supplies that drive motors.It is a very ideal power electronic device for variable frequency speed regulation, metallurgical machinery, electric traction, servo drive, and variable frequency household appliances.
