Problems solved by technology

[0009] The drive system of the current inverter air conditioner is composed of three components, which is high in production cost, low in reliability, and difficult in the wiring of the circuit system.
With the increasing usage of inverter air conditioners, the failure cases of inverter air conditioners are also increasing, and more than 50% of the failures of inverter air conditioners occur on the existing drive system; in addition, the price of inverter air conditioners is higher than that of fixed frequency air conditioners , reducing the manufacturing cost of inverter air conditioner drive system has also become an important issue

Abstract

The invention discloses a high-integrated intelligent power module, wherein a logic control circuit and a drive circuit are arranged in the high-integrated intelligent power module IPM3, the high-integrated intelligent power module IPM3 generates two paths of output, the first path of output is U3, V3 and W3, the second path of output is U4, V4 and W4, wherein the first path of output drives an inverter compressor M3 of an inverter air conditioner, and the second path of output drives an inverter fan M4 of the inverter air conditioner. The high-integrated intelligent power module IPM3 comprises a control chip MCU2, a high-voltage integrated circuit HVIC3, a first analog switch K1, a second analog switch K2 and a third analog switch K3, wherein the control chip MCU2 controls the high-voltage integrated circuit HVIC3 through a first control signal PRO3, and controls the first analog switch K1 through a second control signal PRO4. The high-integrated intelligent power module has the characteristics of simple and reasonable structure, flexibility for operation, low manufacturing cost, high reliability and wide application scope.

Description

technical field [0001] The invention relates to an intelligent power module, in particular to a highly integrated intelligent power module. Background technique [0002] Intelligent power module, namely Intelligent Power Module, abbreviated as IPM, is a power drive product that combines power electronics and integrated circuit technology. The intelligent power module integrates the power switching device and the high-voltage driving circuit, and has built-in fault detection circuits such as overvoltage, overcurrent and overheating. On the one hand, the intelligent power module receives the control signal from the MCU to drive the subsequent circuit to work, and on the other hand, it sends the system status detection signal back to the MCU. Compared with traditional discrete solutions, intelligent power modules have won an increasing market due to their advantages of high integration and high reliability. They are especially suitable for inverters and various inverter power ...
