摘要：

An algorithm is presented for the computation of the saturation characteristics of transformer iron cores based on supplied conventional V(rms)-I(rms) curves and no-load losses at rated frequency. Laboratory measurements on a steel sample were carried out. It is shown that the iron core losses are a nonlinear function of the applied voltage. Taking these losses into account improves the nonlinear flux-current characteristic.
