ABSTRACT


The high-gain DC to DC Converter widely used in industrial and power system applications. In particular, the non-isolated converters are highly prepared due to their size and cost. The application such as photo-voltaic (PV) and wind power system, the combination of non-isolated converter and inverter are used. These converters are selected for the specific applications depend on the circuit complexity, reliability and cost. With respect to PV applications, the simple boost wider range voltage gain DC to DC converter is better choice to meet the DC-link voltage of the PV inverters. Comparing with conventional inverters, multi-level inverters (MLIs) are the worthy option, as it has a superiority to suppress the voltage and current harmonics. Even though the reduced switch MLIs are well-established for medium voltage PV system, still the challenges beside to improve voltage harmonic, voltage enhancement, increasing the inverter efficiency etc. Hence, in this paper proposes the PV Power system with single switch non-isolated high-gain DC to DC converter and reduced switch seven-level MLI inverter. The proposed converter is developed with the mixtures of boost and cuk converter; hence it has wider range of control with good efficiency. The experimental study of 400W PV system is established. The experimental results are conformed the theoretical investigation.
