Based on the high-performance motor control SoC - CMS32M5710L048, a cost-effective single-resistor non-inductive FOC inverter refrigerator compressor drive solution has been developed. The reserves of touch and main control chips are also abundant, which can form a complete solution for the refrigerator system.
CMS32M5710L048 Refrigerator compressor drive scheme performance characteristics:
> The main control chip CMS32M5710L048 adopts Cortex M0 ultra-low-power core, the main frequency is up to 64MHz, built-in 2-channel high-performance op amp, equipped with enhanced PWM, easy to realize single-resistor sampling, reduce BOM cost
> The drive part adopts the discrete mode of mainstream high voltage Gate drive IC + IGBT
> The driving algorithm is mature, it has matched more than 30 refrigerator compressors, and can complete all the matching work of one compressor in half a day
> The intelligent startup algorithm can easily cope with various load conditions, and the startup success rate is 100%
> Complete protection mechanism to quickly and effectively protect the motor system and prolong the service life of the product
> Advanced control algorithms such as harmonic injection, torque compensation and zero-speed start can be selected
