Abstract

The invention relates to an intelligent power module driving circuit, an intelligent power module and a household appliance. According to the intelligent power module driving circuit, the intelligent power module and the household appliance, a first bridge arm switch device and a second bridge arm switch device are separately driven to be switched on alternately through a first driving device and a second driving device in the operation process, so that a switch control function is realized. Moreover, when the negative voltage caused by the parasitic inductance of the bridge arms or the voltage caused by a Miller effect is too high, clamping is carried out through a first voltage stabilizer or a second voltage stabilizer, so that the voltage transmitted to the first bridge arm switching device or the second bridge arm switching device is not enough to drive the first bridge arm switching device or the second bridge arm switching device to be switched on, so that the misconduction phenomenon caused by the parasitic inductance and the Miller effect can be effectively avoided, the direct connection of an inverter bridge arm and the explosion of an intelligent power module are avoided, and the working reliability of the intelligent power module is improved.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, in particular to an intelligent power module drive circuit, an intelligent power module and household appliances. Background technique [0002] Intelligent power module (Intelligent Power Module, IPM) is an advanced power switching device, which integrates logic, control, detection and protection circuits, which is easy to use, not only reduces the size of the system and development time, but also greatly enhances the It ensures the reliability of the system, adapts to the development direction of modularization, compounding and power integration of power devices, and has been widely used in power electronic devices represented by frequency converters and various power supplies. [0003] The switching device inside the intelligent power module is usually IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor). When using a high-performance IGBT drive circ...
