Because of different rectifier circuits require different rectifier transformer design, dualzone balance Reactor rectifier circuit and bridge rectifier circuit, the DC in the same load shedding his arm is the current average of the bridge rectifier circuit half, and the pressure drop is of the latter half, they have been widely used in low voltage high current systems. But due to the increase in the balance reactor has increased transformer plexity and many hidden problems. Canceled balance Reactor five threephase transformer rectifier is precisely to overe the balance of Reactor shortings. On the question of research on practical issues contrast system is used bridge rectifier circuits or dualrectifier circuit to be analyzed Reactor balance the implicit and shortings. And the cancellation of balance reactor using threephase rectifier transformers five pole design advantages, the theoretical basis, Transformer design calculations for single device choice， and the mapping of the overall layout. As a practical engineering design issues, paper discussed by the majority of thinking in laboratory experiments to be successful, Experimental results show that the abolition of Reactor balance threephase rectifier transformers5 with a good performance.
