The scheme solution of air conditioning-士兰微电子英文官网

Silan provides a complete set of solutions on the electronic control scheme of inverter air conditioning, including MCU master control scheme, IPM for compressor, IPM for fan, ACDC chip, PFC related (PFC driver chip, IGBT, FRD) circuits.

Permanent magnet synchronous motor (PMSM) is widely used due to its advantages such as high efficiency, small size, simple structure and fast dynamic response.For air conditioning applications, the overall solution provided by Silan adopts "MCU(SC32F58128)+ dual IPM+ACDC+PFC", which can simultaneously control air conditioning compressor, DC fan and PFC.The motor control adopts the method of single resistance sampling, and at the same time through the sensorless algorithm to effectively reduce the cost of the electronic control scheme, and has the advantages of fast start-up speed, strong load capacity, etc., this control method combined with the whole set of scheme of Silan can make the customer's electronic control BOM cost reach the lowest level in the industry.
