INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY SIMULATION OF TRANSFORMERLESS DC- DC BOOST CONVERTER FOR HIGH STEP-UP VOLTAGE GAIN
2016
This paper presents the performance analysis of transformer less dc-dc converters to achieve high step-up voltage gain without an extremely high duty ratio. The technique used to design the equivalent circuit of these converters is switched-inductor with voltage lift circuit, allowing a boost of the input voltage to high values. In this paper describes the steady-state analysis of voltage gain for all the converters(dc-dc step up, dc-dc step dawn). For the execution of proposed converters the MATLAB/SIMULINK software has been used. Finally the comparative analysis of proposed converters with conventional boost converter which shows that proposed converters have higher voltage gain and reduced voltage stress.
