摘要：

In this paper the authors present a technique based on the use of a virtual air gap which equivalent thickness varies in function of controllable parameters adapted to the configuration of the magnetic circuit and the associated control system, The principle is presented using a magnetic circuit similar to a transformer one. Among the numerous applications, this technique can be applied to reduce inrush current in single-phase transformers.
