Refrigerator Compressor Reference Design

Nidhi Agarwal
By Nidhi Agarwal

The reference design enhances refrigerator efficiency and reliability by enabling advanced compressor control for modern refrigeration systems.

Refrigerator compressors have transitioned to using brushless DC motors or permanent magnet synchronous motors for higher energy efficiency. An inverter-based variable speed drive is essential for these brushless motors, allowing the compressor to operate at optimal speeds and maintain a constant temperature more efficiently than traditional fixed-speed single-phase AC induction motor (ACIM) drives. Field-oriented control (FOC) with brushless motors enhances the implementation of variable speed drive. It adds advanced motor control features like on-the-fly startup and stall detection with auto-recovery.
