Abstract :
A current sensor is developed which can detect with a fast response and with precision the instantaneous current including higher harmonic components, such as an inverter output current. The proposed sensor can reconstruct an instantaneous current chopped up into the frequencies of several tens of kilohertz with an accuracy of 0.5% FS (full scale). The detectable range covers currents from on the order of milliamperes to several amperes.<>
