Summary:This paper proposes a modified Cuk converter to achieve the high voltage ratio for applications that needs of high voltage. The circuit configuration of proposed converter is simple and consist of just one switch, two diodes and include several energy storage components. Using a single switch reduces the implementation and switching costs and switching power diminutions. The presented converter has continuous input and output current. The input current has low ripple which low input current ripple helps maintenance of renewable energy sources because they degrade when considerable currents are drowned from them. The proposed converter provides continuous output current which decreases the current stress on the load terminal capacitor. It has two operation modes in continuous conduction mode (CCM). The output voltage ripple of the proposed converter is low, the voltage stress across switch and diodes are slight and lower than the converters output voltage. The mathematical analysis and MATLAB simulations of the proposed converter has been proved that topology of the proposed converter has proper performance and effectiveness.
