Abstract: Power electronic technology based energy conversion can be applied towards electric vehicles and renewable & alternative energy generation systems. In this approach battery pack is the prime concern since it is used for energy storage. So it is important to pay more attention for charging/ discharging and power management. The system response improvement and battery protection can be achieved by ultra capacitors. Conversion systems using power electronics technology basically contains generators, converters, power storage and inverters. In this paper to reduce cost and increase the efficiency of power conversion multimode single leg power converter is introduced. This converter provides the function of boost as well as bi-directional converter. Hence efficiency and fault tolerance capability of the system is improved. In the proposed system there are four modes of operations. Each mode is simulated using MATLAB SIMULINK.
Keywords: multimode converter, conversion system, power management, MATLAB SIMULINK.
