Description
technical field [0001] The invention relates to the technical field of power semiconductors, in particular to an intelligent dual-drive IPM frequency conversion controller and an air conditioner. Background technique [0002] Intelligent Power Module, or IPM (Intelligent Power Module), is a power drive product that combines power electronics and integrated circuit technology. It is used in frequency conversion motor servo drives and is widely used in frequency conversion control of household appliances. 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. [0003] In the existing inverter air conditioner, the traditional inverter drive scheme is a drive mode composed of multiple power drive devices with different power ranges, resulting in many power drive devices in the existing inverter air conditioner, which is not conducive to th...
