Abstract

The invention relates to an intelligent power module and an intelligent power module structure using the same. The intelligent power module comprises an MCU, a plurality of inverter circuits and driving circuits for respectively driving the plurality of inverter circuits, wherein an output end of the MCU is respectively connected with control ends of the driving circuits, and the MCU and the driving circuits are arranged close to each other. Compared with the prior art that an MCU is independently and externally arranged relative to an IPM module, the intelligent power module can greatly shorten the length of a control signal line of the MCU, and greatly shorten a path transmitted to the driving circuits, so that the influence of peripheral strong current or electromagnetic signals on a control signal is greatly reduced, the anti-interference EMS capability of IPM work is enhanced, and the working reliability of the whole IPM module is improved.

Description

technical field [0001] The invention relates to an intelligent power module and an intelligent power module structure using the same, belonging to the technical field of power semiconductor devices. Background technique [0002] Intelligent Power Module, or IPM (Intelligent Power Module), is a power drive product that combines power electronics and integrated circuit technology. The current IPM modules generally use a single IPM module to drive a single load such as a motor. In the application scenario that needs to drive multiple loads, the controller needs to be equipped with multiple IPM modules. Because the IPM module takes up a lot of space, this leads to multiple IPMs. The space occupied by the modules increases a lot, which increases the area of ​​the entire controller, which is not conducive to the miniaturization installation requirements of some controllers while increasing the cost. Contents of the invention [0003] The technical problem to be solved in the pr...
