For refrigerators and freezers (like all large appliances), energy efficiency and noise-free operation are key design considerations. But unlike other appliances, they need to run continuously, making energy efficiency more important. In addition, they are becoming more and more connected in order to take advantage of the opportunities provided by cloud connections and mobile applications to monitor the humidity and temperature of food in the refrigerator. To help design high-efficiency motor control solutions suitable for various motors used in these devices (such as three-phase brushless motors, general motors, etc.), ST provides a wide range of STM32 microcontrollers, power MOSFETs, IGBTs and intelligent power modules (IPM) , SCR and AC switches, high-voltage pre-drivers, and a full set of hardware and software evaluation and development tools. In addition, ST also has a variety of advanced MEMS motion and environmental sensors, as well as wired and wireless connection solutions, which can help design refrigerators and freezers that are networked, efficient and easy to use.
