Abstract:
We developed a printed circuit board “Rogowski coil” to improve the reliability of power modules and packages. For the design, we used a new tool for sensitivity and adopted a fishbone coil pattern to realize design sensitivity. The developed coil demonstrates flat sensitivity that is as good as that of commercialized current probes/sensors because the proposed coil pattern successfully cancels noise from an outside current with flat signal sensitivity by an inside current.
