An interleaved zero-voltage zero-current switching (ZVZCS) high step-up DC-DC converter is proposed for modern photovoltaic power generation systems. The can achieve voltage conversion gain without operating under extreme duty cycles. be readily adjusted by selecting different numbers of the diode-capacitor multiplier (DCM) cells in circuit at design stage. Moreover, with passive snubber conver...

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.
