12-cycle converter for use in electrical motor control system, has unit that generates additional magnetic leakage flux at level of interface inductors in order to integrate smoothing inductor

摘要

The converter has an autotransformer (3) with a primary coil (5) connected in triangle. Two star connected secondary coils (7) are connected to two rectifier bridges (11, 13) whose parallel functioning is ensured by two interface inductors (15, 17). A unit generates an additional magnetic leakage flux at the level of the interface inductors in order to integrate a smoothing inductor (15b). An independent claim is also included for a control system of an electric motor including a 12-cycle converter.
