Study on Simulation Model of Aviation Auto-Transformer-Rectifier Unit

This paper researched 24-pulse aviation auto-transformer-rectifier unit(ATRU).Against that traditional 24-pulse rectifier transformer’s weights are too large while circuit efficiency is low,and delta connected autotransformer’s windings are too complex and the circuits are hard to achieve,this paper researched a star connected autotransformer based ATRU.The structure and principle of the circuit were analyzed,and the expression of input line current’s harmonic amplitude was derived.ATRU’s simulation model was built by using Saber software.The experiment proves that the simulation results and theoretical analysis results are completely consistent.The correctness and feasibility of the proposed 24-pulse rectifier circuit based on star connected autotransformer is verified by the theoretical analysis and simulation experiment.
