New prospective topologies of magnetic-regulated rectifiers for aircraft power supply systems

New circuit solutions of magnetic-regulated rectifiers on the basis of controlled single-winding saturable inductors for aircraft power supply systems are proposed in this paper. It is offered for cores of magnetic switches to use modern soft magnetic amorphous and nanocrystalline alloys which have advantages over traditional magnetic materials for similar applications. Presented and analyzed the results of modeling of the proposed topology of the three-phase magnetic-regulated rectifier with the LC-output smoothing filter in transition and emergency modes. Based on results of the computer simulation it is shown that the single-winding saturable inductor included in the secondary circuit of the rectifier is able to regulate the output voltage of the device and to ensure protection from load short circuit.
