FAQ

Q1: What is a closed loop Hall effect current sensor and how does it work? ❯

A closed loop Hall effect current sensor uses the Hall effect principle to measure current while employing a feedback loop to maintain zero magnetic flux in the core. When current flows through the conductor, it generates a magnetic field that is detected by a Hall element. The sensor drives a compensation current through a secondary winding to cancel this magnetic field, and the feedback current becomes proportional to the primary current. This closed-loop mechanism improves accuracy, linearity, and response time.

Q2: What are the key advantages of using a closed loop Hall effect sensor over an open loop type? ❯

Closed loop Hall sensors offer higher accuracy (typically ±0.5% or better), faster response times (less than 1 μs), and superior linearity. They also have a better temperature stability and lower offset drift. These features make them suitable for high-precision applications in power electronics, industrial drives, inverters, and motor control systems.

Q3: Can the Hall effect current sensor measure both AC and DC currents? ❯

Yes, the sensor can accurately measure AC, DC, and even pulsed currents, making it versatile for various applications including power converters, battery management systems, and variable frequency drives.
