Backup power bidirectional charging and discharging control has been an important problem for ship manufacturing and control. In order to solve shis problem,this paper presents the intelligent control system design of a peak current-mode controlled multi-module bidirectional ship backup battery charging / discharging converter. And this system can be used to ship multi module backup power backup power effectively. The reduced-order modeling technique is combined with the small-signal model of current mode control, leading to design procedures for both current sensing network and voltage feedback compensation. Result of small signal simulations experiment demonstrates the availability of the proposed intelligent control system design.
