霍尔效应电流传感器

1. The Hall Effect: Translating Current in Magnetic Fields Hall current sensors operate on the Hall Effect—when current flows through a conductor perpendicular to a magnetic field, charge carriers deflect under Lorentz force, generating a voltage (VH) proportional to magnetic flux density.   The formula is:VH = (RH × I × B) / d(RH: Hall coefficient; I: Current; B: Magnetic field; d: Material thickness). This enables non-contact current measurement, eliminating contact loss and high-voltage risks in EVs and smart grids.   2. Precision Evolution: From Open-Loop to Closed-Loop Two core technologies dominate: Open-Loop (e.g., Token TKC Series) Simple structure, cost-effective (40% savings) Ideal for industrial drives and UPS Closed-Loop (e.g., Token TBC Series) Compensation coils generate counter-magnetic fields to maintain "zero flux" Accuracy up to 0.1%, temperature drift <±10ppm/°C, critical for EV motor contro Closed-loop’s anti-interference capability shines in 200kHz SiC switching noise environments. Combined with electromagnetic shielding (Faraday cages), it suppresses >60dB common-mode noise.   3.
