**7. Conclusion**

The periodic testing and discharging the batteries to ensure the capacity and availability of battery systems is mandatory in nuclear power plants. The batteries of large power capacity are discharged with the regenerative technology to the grid by utilizing this technique. The design intents of lower current ripple and output voltage ripples is realized with the interleaved boost converter topology. The Harmonics in AC Output is well minimized with the help of optimum LC Filter design. This paper is conceptual base for designing high power battery regenerate discharge system without disturbance to normal plant operation with grid. A 100A Boost converter prototype model was assembled and was paralleled with 6 similar units for 600A Current capacity. Thus, the proposed design has a huge capacity to deliver energy savings, output voltage and current regulations with very minimum net harmonics for wide range of discharge currents and voltages.
