Paper Details

Multilevel inverters are widely used presently withnon conventional energy sources like solar, fuel cell. The sourcehas lower individual voltage level. Conventional invertertechnique uses bulky transformer and high rating devices whilein multilevel inverter there is no transformer and level is boostedby cascading switching devices in particular order. Naturally thewaveform is not pure sine and harmonics are present. The paperdescribes. The proposed methodology was based on the nonconventional sources produce low level voltage levels. It makemultilevel inverter technique is useful. The application partconsists of real requirement in rural area where there is loadshading problem to preserve vegetable where supply source isonly solar energy. Our system is suitable in area whereuninterrupted supply is required like food preservation & kidneydialysis system.Here 7level MLI is considered for analysis.
