Design and Analysis of Novel Cascaded Topology with LD Cell for Micro-source Grids
Keywords:Novel, Cascaded, Topology, Microsource, Application
This paper focus on DC-DC converter called Novel Cascaded topology. This converter lies in the category of Non-Isolated DC-DC boost converters with upgraded voltage gain based on conventional topology with LD cell for micro-source grids. The proposed novel cascaded topology increases the voltage boost ability. There are some merits of our proposed topology that includes small voltages stresses across the switch, as well as upgraded gain. We prefered to use switch having small voltage rating as well as small resistance in ON-mode (RDS-ON), it leads to provide high efficiency. In our cascaded topology with LD cell,we did not use large duty cycle, coupling inductors as well as transformer.We will utilize the Continuous Conduction Mode (CCM) for the analysis of proposed novel cascaded topology. This topology is designed to operated on 12V supplying voltage, 55% duty cycle, 265W output power and frequency of 12KHz. The continous conduction mode (CCM) has been analyzed theoretically as well as practically based derived equations. The novel cascaded converter has been simulated in PSIM as well as MATLAB/SIMULINK, while explanations of the overall results are provided based on PSIM.
