Variable Inductor Design Method for Rectifiers at Railway Substations

抄録

This paper describes a new voltage adjustment technique and its design method. In the new design, a voltage compensator, comprising a variable inductor and a controller, is connected with a transformer and a rectifier on either side in series. The authors developed a new configuration of the variable inductor suited for railway application, with a focus on six-phase AC and large current capacity. A fast simulation method for designing the inductor was developed based on the magnetic flux circuit theory and the non-linear simulation technique for ferromagnetic materials.
