Nowadays, when purchasing a refrigerator, consumers not only consider external factors such as appearance, capacity, and price, but also pay more attention to the energy-saving effect of the refrigerator. As the main component of refrigerator energy consumption, the quality of the compressor largely determines the refrigerator's refrigeration capacity, energy efficiency level and noise level. Therefore, when designing products, manufacturers should choose efficient compressor solutions to meet the needs of intelligence, compactness, energy saving and low cost. The refrigerator compressor solution launched by Dalian Dapinjia based on Infineon IMC101T can meet increasingly stringent energy efficiency regulations and help companies create highly economical products.

This solution is based on the Infineon iMOTION™ smart driver , which combines a ready-to-use FOC motor control algorithm and combines the digital motor control IC (iMOTION) IMC101T-T038 with a three-phase CIPOS™ Micro smart power module. This combination provides a full-featured compact inverter solution for low-power motor drive applications, ideal for customers seeking higher integration and smaller size.

IMC101T-T038 is a product of the IMC100 series with built-in Infineon's next-generation motion control engine (MCE 2.0). The engine not only enables field-oriented control (FOC) but also eliminates the need for software coding when developing motor control algorithms.
