内容記述
This paper proposes a current measuring system using a tiny sensor based on a rogowski coil and an analog circuit. The sensor picks up a switching current and the analogue circuit converts it to an out put signal following the output current of a converter. The system can detect not only ripple component but also dc component of the output current, although the rogowski-coil-based current sensor is employed. The system will be emvedded in an intelligent power module.
