High Current, High Bandwidth Current Measurement Techniques

Accurate current measurement plays a key role in testing and verifying power electronic circuits. This paper compares four different types of high-current, high-bandwidth measurement techniques. A compact linear Rogowski Coil with integrator circuit is built and tested. The test results presented in this paper show this current sensor to be compact, accurate, and with a bandwidth of greater than 100MHz.
