Design and Development of PV Powered Intergraded DC - DC Converter Fed Multilevel Inverter for Standalone Application

The use highlighter amount of nonconventional energy is causing greenhouse gas emissions worldwide, which is affecting the climate adversely. To avoid this, all counties keen to swapping conservative energy foundations to non-conservative foundations. There are variety of DC to DC converters reported in literature with various power-boosting performances which comprises of energy storing passive elements (in capacitors and inductors), with either 1: n transformers in aggregation along with power electronics switches (MOSFETs and Diodes), which are named as isolated and non-isolated converters respectively. These converters are selected for the specific application depends on the circuit complexity, reliability and cost. Sometimes, the reduction of power circuit components and/or power switches is need to this converter industry to meet out the growing demand, cost, and size. With respect to PV application straightforward increase larger voltage gain DC to DC converters are an option and this should a coordination to operate with DC to AC converter (inverter). Compare to the conventional 2-level inverter, multilevel inverter (MLI) is a better selection since it has a quality to suppress the harmonic distortion on the current and voltage. Although reduced switch MLI have been well recognized as a striking resolution for intermediate power PV and wind power generations’ claims, still challenges and opportunities are looking forward for the reduction voltage harmonic, voltage profile enhancement, increasing the voltage transfer gain, reduction in the switching losses etc. Hence, the proposed is dealt with a suitable high efficient DC to DC converter and MLI inverter can be improve the stand-alone PV power system. In this work, the generalized simulation and practical implementation of PV connected single switch performed seven-level MLI for 100W PV system The suggested work accurately models the relationship between voltage gain and boost duty ratio using theoretical data. investigation is verified experimentally.
