Electrolyte-Free Inverter Board for Refrigerators
This refrigerator controller is primarily used in compressor control scenarios and is compatible with various mid-to-low-end refrigerator across different product categories.
Product Advantages
Compact size and high integration with significantly reduced overall dimensions; modular design with high EMC margin.
Maximum torque-per-amp ratio, space vector modulation, and overshoot control reduce switching losses, improving efficiency by 2%.
Field weakening control technology enables higher motor operating speeds.
Torque compensation reduces noise and vibration by over 90%, with harmonic reduction also exceeding 90%, ensuring stable and efficient low-frequency compressor operation.
Undervoltage frequency reduction and deceleration shutdown strategies reduce compressor wear and extend lifespan.
Nanosecond-level overcurrent protection, under/over-voltage protection, and overcurrent/overpower protection. Fault protection logic safeguards both drive circuitry and compressor, ensuring extremely low failure rates and low PPM.
