Design of a Partial Resonant Inverter for solar photovoltaic applications

This paper presents a solar-powered Partial Resonant Inverter (PRI) interfaced with an asymmetrical cascaded nine-level inverter. The DC input of the proposed system is obtained using Solar Photovoltaic (SPV) panel. sources fed to inverter are in ratio 1:3. step modulated works precalculated switching angle for fixed modulation 0.7. Compared conventional 50 Hz and multi-output transformer design, more compact because high-frequency AC link. PRI ensures Zero Voltage Switching (ZVS) reduces losses. scheme has been validated MATLAB/ SIMULINK environment experimental prototype built laboratory. Based on investigations Selective Harmonic Elimination (SHE) method gives superior performance when compared Optimal Stepped Modulation (OHSM) method. From results comparative analysis, uses fewer switches obtain output, setup multioutput make design improves power quality system.
