When high-order harmonics push EMC over limits, traditional designs incur extra filtering cost; low-frequency compressor vibration triggers system resonance; insufficient PFC efficiency drives up operating expense. As a leading provider of VRF air conditioning system and HVAC variable refrigerant flow systems solutions, our BLDC motor controller and 3 phase brushless motor driver technologies deliver:

• 180° Sine Wave Vector Control (torque ripple < 5%) — ideal for 3 phase brushless motor driver applications.
• Adaptive Vibration Suppression (mechanical vibration reduced by 50%) — makes for a more reliable compressor driver board.
• High-Frequency Flux-Weakening Technology (speed regulation range 15:1)— ensures constant torque over a wide speed band.
• MTPA Control (copper loss reduced by 8% in commercial compressors) via sensorless BLDC controller and BLDC FOC controller.
• Proprietary Compressor Core Algorithm (compatible with mainstream compressor brands and R410A/R32 refrigerant systems)— the heart of our heat pump controller and inverter heat pump for swimming pool designs.
• Integrated High-Frequency PFC Inductor (THD < 5%) in our PFC power supply modules.
• Magnetic Saturation Compensation (iron loss reduced by 12% in commercial compressors).

Applications: VRF air conditioning systems, solar-powered ACs, commercial central air conditioning (ducted/ceiling-cassette/modular units), and refrigeration/freezing compressors. Provides safety-precompliant PCB architecture, supports split or integrated controller-driver layouts and refrigerant-cooled PCB processes.
