| Abstract: | Thyristor is a main part of fault current limiter(FCL) which will endure bulk current stress during turn-on and conductive process,while existing high power electronics test equipment cannot satisfy the requirement of over-current test.Based on the analysis of thyristor operation condition,equivalent test parameter and method are proposed.According to power electronics equivalent test theory,the losing validity mechanism for thyristor is analyzed.Equivalent test indices are obtained through building over-cu... |
