Against that tradi-tional 24-pulse rectifier transformer' s weights are too large while circuit efficiency is low, and delta connected auto-transformer' 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 ex-periment 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 the-oretical analysis and simulation experiment.
