Abstract

An intelligent power module for an air conditioner and the air conditioner are provided. The intelligent power module comprises a low-voltage area power supply positive end, a low-voltage area power supply negative end, a high-voltage power supply positive end, a high-voltage power supply negative end, a PFC interface, a direct-current interface and an alternating-current interface, and comprisesa first HVIC tube used for driving the compressor to work; a plurality of second HVIC tubes in one-to-one correspondence with a plurality of fans, with each second HVIC tube being used for driving thecorresponding fan to work; a PFC circuit respectively connected with the high-voltage power supply positive end, the high-voltage power supply negative end, the PFC interface and a PFC control signaloutput end; and a rectifier. According to the intelligent power module, the first HVIC tube, the plurality of second HVIC tubes, the PFC circuit and the rectifier are integrated into a whole, so thatthe frequency conversion control of the compressor and the plurality of fans is realized, a packaging process flow of the IPM can be simplified, the equipment cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an intelligent power module for an air conditioner and an air conditioner. Background technique [0002] IPM (Intelligent Power Module, Intelligent Power Module) is a power drive product that combines power electronics and integrated circuit technology. It is widely used in frequency conversion control of household appliances and servo drive of frequency conversion motors. 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 frequency conversion one-to-multiple solution of the air conditioner, the outdoor main control board needs to use more than two fan-driven IPM modules, and there are many types of power switching devices, the plug-in process is cumbersome, the production efficiency is low, and the cost is high...
