Novel Low-Cost Closed-Loop Compensated Current Transducer with Enhanced Performance

摘要

A low-cost closed-loop current transducer with enhanced measurement performance is presented. The working principle, main design choices, FEM simulation results and laboratory test measurement results are explained. The paper shows the transducer development process starting from CAD design, continuing with simulations, a prototyping phase, and finishing with tests and measurements to confirm the achievement of the design goals. Those main product design targets are requests coming directly from the market where low-cost and, at the same time, high performance current transducers are demanded.
