The paper provides an overview of coreless open-loop current transducers based on Hall effect sensor CSA-1V. Depending on the implementation method and current range, the presented transducers are divided in the four groups. The transducers are capable to measure AC and DC currents ranging from several tens of miliamperes up to several hundreds of amperes. Methods for resolving issues with the skin effect and stray magnetic fields are also presented including the experimental test results. Some of these methods are novelty and have never been presented in literature.

“…According to Mizuno et al [8], the magnetic permeability and resistivity of the coating should be higher than those of substrate. High permeability allows magnetic field to pass through the coating, while high resistivity lowers eddy current loss.…”

“…Mizuno et al [8] measured the eddy current loss of copper wire and magnetoplated wire, which is a copper wire whose circumference is plated with a magnetic Fe film. Their results showed that the eddy current loss in the magnetoplated wire was reduced to a factor of 0.25 or less in comparison with that in copper wire.…”

“…However, it is difficult to have a uniform finish because of the dripping of the coating material during the spraying; poor adhesion occurs due to chemical compatibility. In addition, the wet plating method and the spray method suggest that the skin effect may be enhanced in the high-frequency band because the magnetic film is not an insulator [10].…”

In today's fast‐paced environment, the downsizing of electronic devices has become imperative. A high driving frequency is effective for the downsizing of electronic equipment. However, one problem with high driving frequency is that it increases the ac resistance and heat generation on passive devices. Using a magnetic coating on the copper wire can effectively reduce the ac resistance. In this study, we propose a method for wrapping a magnetic tape around a copper wire to easily provide a uniform magnetic coating for reducing the ac resistance. In the magnetic field simulation, we reduced the proximity effect in the coil by using a magnetic tape. The temperature rise at the thermal saturation was reduced by 26% for the experiment with a high‐frequency current of 4 A. Applying the magnetic tape to a single‐wire coil effectively reduced the ac resistance and heat generation. © 2020 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.
