Design of Closed-loop Inverter Using High Gain Converter

The Recent technological advancement of Power Electronics field have utmost importance for renewable energy applications like solar, wind etc. Voltage generally obtained from PV cells are converted to high voltage with better efficiency using Power electronics converters. In this paper, the proposed non- isolated high gain converter is utilized to serve that purpose in place of conventional boost converter. The source voltage is kept varying 9 (v) to 25 (v) and feedback mechanism is implemented to obtain desired voltage as output. The converter is connected with the Single-phase Voltage Source Inverter (VSI) which is operated with SPWM switching technique. The voltage at output end is attained constant of the inverter with implementation of closed-loop mechanism. It provides sustainable operation with better stability of the system. The simulation is performed in MATLAB for R and R-L types of loads. Reduction of harmonic contents are performed using suitable design of filter and smoothen output signal of Inverter and keep it within IEEE standard limit.
