Abstract Based on the influence of circuit element tolerances to the k-fault diagnosis, a method of fault diagnosis is presented which is called as minimum tolerance estimation algorithm and has clear physical meaning. Using this method, an effective estimation of the equivzlent fault sources can be obtained with less computing time. It is especially worthwhile to point out that a self-adaptive sub-optimal algorithm, which comes from the above method, requires even less computing-labor and is particularly suitable for more complicated circuits as well as real-time fault location.
