Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 Shown is the external pin schematic diagram of the present invention. The present invention utilizes new materials to fill the assembly process, and reduces conventionally defined external pins without increasing the volume of the IPM for packaging. The present invention only needs 17 pins, including: DC power supply pins (pin 1 and pin 2), error output signal (pin 3), six-way PWM control signal (pin 4-pin 9), three-phase N-terminal current detection signal (pin 10-pin 12), power side DC (pin pin 13 and pin 17), three-phase output pins (pin 14-pin 16). By greatly reducing the external pins of conventional IPMs, the present invention makes the IPMs more integrated and more reliable, thus making its application and system construction easier.

Abstract

The invention provides a high-integration intelligent power module, comprising a shell and a power base plate, wherein, the shell is internally integrated with a power module, a driving module as wellas a built-in auxiliary module; the built-in auxiliary module at least comprises a suspension power supply module, a parallel plate capacitive matrix module, a time constant setting capacitive module, a short-circuit protection module, a three-phase N-end current detection module and a temperature detection module. The high-integration intelligent power module is applicable to driving a frequencyconverter of a motor and various inverse power supplies.

Description

technical field [0001] The present invention relates to an intelligent power module (High-Integrated Intelligent PowerModule, abbreviated as HIPM)), in particular to a highly integrated intelligent power module (IPM) that uses a new type of module (circuit) to further improve the integration of the intelligent power module (IPM). module. Background technique [0002] The intelligent power module, namely IPM (Intelligent Power Module), not only integrates the power switching device IGBT and the driving circuit, but also has fault detection and protection functions such as undervoltage, overcurrent and overheating, and can output error signals to the CPU . Therefore, the system using the intelligent power module can still ensure that the IPM itself is not damaged in the event of a load accident or improper use of the system. IPM is winning more and more markets with its high reliability, low loss and low development cost, especially suitable for frequency converters and vari...
