This paper presents the design and simulation of modified step-up converter with high voltage gain using quasi switched inductor capacitor. High Voltage are major requirements for renewable energy applications. The operating modes is analyzed proposed simulated MATLAB/SIMULINK platform. Key Words: gain, converter, lower duty ratio.

The main purpose of this paper is the development a DC/DC boost converter with high conversion efficiency. proposed has step-up ratio and equipped soft-switching technology. inductor used in developed coupled rather than general inductor, therefore, voltage can be improved, so that characteristics power switch obtained within same duty cycle. connected to resonance branch circuit traditional co...
