M.Shanmuga Priya, P.Parthasarathy, R.Saran Raj

A suitable DC-DC converter is required for designing high efficiency power systems. Among the various topologies, Multidevice Interleaved Boost converter (MDIBC) is considered as a better solution for high power systems due to improved electrical performance, reduced weight and size. Detailed analysis has been done to investigate the benefits of multidevice interleaved boost converter compared to the conventional boost converter topologies. By virtue of the converters, the input current can be shared among the cells or phases, so that high reliability and efficiency in power electronic systems can be obtained. In addition, it is possible to improve the system characteristics such as maintenance, repair, fault tolerance, and low heat dissipation. Moreover, the overall performance of the compromised design was shown to be quite good. The dc/dc converter topologies are designed for water pumping system and investigated the DC motor characteristics by using MATLAB/ Simulink.
