This digest presents the phase current reconstruction for a planar Rogowski coil current sensor with a reset-free analog integrator circuit. By utilizing the aforementioned Rogowski coil-based current sensor, this work aims to provide an alternative to the commonly employed Hall-effect current sensors. The sensor's design, the phase current reconstruction technique, and the accompanying design recommendations are discussed in detail. Continuous testing has been performed. The experimental results demonstrate an accurate current measurement performance that is comparable in both dynamic and static regions to that of an ac/dc current sensor.
