Air conditioner and integrated air conditioner controller

Abstract

The invention discloses an air conditioner and an integrated air conditioner controller. The controller comprises a base plate, a rectifier bridge, a power factor correction PFC drive circuit, a compressor drive circuit and a compressor control chip. At least one part of devices in the PFC drive circuit and the compressor drive circuit are SiC devices, and the other part of devices are Si devices.A voltage converter is further included and used for generating the conversion voltage according to the power source voltage, when the power source voltage is the first voltage, the voltage convertergenerates the second voltage, when the power source voltage is the second voltage, the voltage converter generates the first voltage, the first voltage is used for supplying power to the Si devices,and the second voltage is used for supplying power to SiC or GaN devices. Accordingly, the manner that the SiC devices replace part of the Si devices is adopted, the voltage converter is arranged so that the drive circuits can be compatible with different switching devices, and performance and reliability of the controller are improved.

Description

Technical field [0001] The present invention relates to the technical field of electric control, in particular to an integrated air conditioner controller and an air conditioner. Background technique [0002] With the continuous expansion of the application range of power electronic technology, increasingly demanding applications and the continuous improvement of people’s requirements for power electronic equipment, the four power devices on the outdoor electric control board of the traditional inverter air conditioner are installed in their respective pin types. On the PCB board, the same heat sink (fin) is used for concentrated heat dissipation, and a new material SiC power semiconductor device with high pressure, high temperature and low loss is used to replace the traditional Si-based power semiconductor device. [0003] However, the problem with the related technology is that if a separate rectifier bridge, PFC switch, compressor IPM, and fan IPM are used for the pin installat...

AI Technical Summary

Problems solved by technology

[0003] However, the problem with related technologies is that if the discrete rectifier bridge, PFC switch, compressor IPM, and fan IPM are installed in a pin-type manner, the outdoor electric control board of the inverter air conditioner will be larger in size, and part of the pin installation cost will be increased. higher
