Cold-start torque drop affects heating stability; water-pump vibration accelerates mechanical wear; traditional PFC response delay reducing PV utilization. Whether you need a thermostat for heat pump or an air source heat pump controller, our heat pump circuit board and 3 phase BLDC motor driver innovations include:

• 180° Sine Wave Vector Control (25% torque boost at-15°C@50% load) — critical for inverter heat pump for swimming pool and other low‑temperature starts.
• Adaptive Vibration Suppression (mechanical vibration reduced by 40%).
• High-Frequency Flux-Weakening Technology (speed regulation range 15:1).
• MTPA Control (copper loss reduced by 15% in heat pump motors).
• Proprietary Compressor Core Algorithm (compatible with mainstream compressor brands and R410A/R32 refrigerant systems).
• Three-Phase Interleaved PFC (efficiency >97.5%, PV interface tracking accuracy >99.5%).
• Magnetic Saturation Compensation (iron loss reduced by 10% in heat pump motors).
• Digital Power‑Switching Module (seamless MPPT input).

Applications: dual-supply/European triple-supply water heaters, swimming pool inverter heat pumps, air-source/water-source heat pump controllers; adopts refrigerant-direct-cooled PCB process (copper substrate + nano-coating), reserves CAN/Modbus interfaces for energy management expansion, supporting -30°C operational drive designs. Also ideal for heat pump circuit board replacement and heat pump control board upgrades.
