The effect of balancing reactor in high power multiple rectifying circuit for electrolytic aluminum was analyzed. The way for calculating the balancing reactor＇s inductance which makes rectifier units parallel working was got though using harmonic to analyze the equivalent circuit of multiple rectifying circuit. On the base of analyzing the critical value, using DC bus to make the effect of balancing reactor was studied. The result of simulation showes that the way for calculating the balancing reactor＇s inductance is correct and the feasibility of using DC bus to make the effect of balancing reactor.
