Abstract :

In this paper Zeta converter fed Multi string multi level Inverter is designed. The use of a high step–up converter is essential for the grid–connected inverter because the input voltage is about 15 V to 40 V for a single PV panel. The proposed converter employs a Zeta converter with a coupled inductor, without the extreme duty ratios and high turns ratios generally needed for the coupled inductor to achieve high step–up voltage conversion; the leakage–inductor energy of the coupled inductor is efficiently recycled to the load. These features improve the energy–conversion efficiency. Here an asymmetrical configuration of Zeta Converter based Eleven–level Multi String Multi Level inverter topology fed Three Phase Induction Motor Drive performance is analyzed. The above results are compared with Multi String Multi Level(MSML) inverter without Zeta converter.
