用于多脉波整流的直线式移相变压器
A Linear-Shaped Phase-Shift Transformer Applied in Multi-Pulse Rectifier
摘要
Abstract
In multi-pulse rectifier systems, to optimize structure and power quality of the ordinary phase-shift transformers, a new type linear-shaped phase-shift transformer was firstly presented. Different from the normal phase-shift transformers, the iron core of the new transformer's iron is linear-shaped and easy to winding arranging and stacking of modules in large power system, and the windings connection is simpler. The principles of the 3/12 phase linear-shaped transformer are then demonstrated. The gas gap translation magnetic field is analyzed, and the harmonic currents on the grid side are suppressed based on the theory of Magnetomotive force balance. The finite element analysis and experiment results of the prototype demonstrate its performance of improving the quality of the output voltages and suppression of harmonic currents in the multi-pulse rectifier systems, and verify the validity of the novel transformer.关键词
