Abstract
A current transformer manufactured with silicon steel laminations has been recently introduced and successfully applied to the measurement of current characteristics of fast switching power modules. Its performance competes advantageously with the existing measuring devices due to its high bandwidth, small physical size, simple structure, galvanic isolation for measurement safety, and low cost as well. In order to have a clear understanding of the working principle of this kind of current transformer for power module current measurement, this paper presents detailed theoretical analysis and design guidelines. Additionally, the error analysis related to the influence of the main geometrical parameters on performance will be given. Design suggestions for achieving higher measurement accuracy by optimizing the current transformer geometrical parameters can be concluded. A prototype of current transformer is manufactured and tested for validating the theoretical analysis. The experimental results agree well with the theory developed in this paper.
