ABSTRACT
Abstract: In this paper, three stage high stepup interleaved boost converter with voltage multiplier cells(VMCS) and three state switching cells(3SSC) is proposed. The new method has been examined under various scenarios, including the loss of switches, ripples and stress. In the proposed topology an additional stage of voltage multiplier i.e, three stages is added which will increase the voltage gain and efficiency, reduces switching and conduction loss, voltage and current stress across switches and ripples. Another important feature of this converter is the lower blocking voltage across the controlled switches compared to similar circuits, which allows the utilization of MOSFETs switches with lower conduction loss. The simulation of proposed converter was done using MATLAB and the stimulation result was validated.
