The portable refrigerator is a household item. Literally, it is a refrigerator that can be carried conveniently. It is smaller, but more energy-saving than traditional household refrigerators, and has cooling and heating functions.

Based on MindMotion’s MM32SPIN0280 microcontroller, the refrigerator compressor scheme takes MM32SPIN0280 as the main control:

- Sliding mode control and primary energy efficiency

- Vibration suppression algorithm and ultra-quiet working mode

- Sensorless FOC and single resistor sampling

MM32 MCU Model:

MM32SPIN0280 Series
