A novel design of Multilevel inverter with reduced switch topology for the integration of renewable energy sources [articol]

Abstract

In recent days, solar energy plays a vital role in providing enormous current for the electrical appliances. Many of the industries manage their electrical issu e with the solar energy. The power losses due to active devices include conduction losses and switching losses. Conduction loss results from the use of active devices, while the switching loss is proportional to the voltage and the current changes for each switching and switching frequency. But, the amount of switching harmonics is attenuated and the power loss caused by the filter inductor is reduced when filter inductor is used. Hence we proposed a new convertor having multilevel inverters which should b e designed with higher voltage levels to improve the conversion efficiency and to reduce harmonic content and electromagnetic interference (EMI). It scores good results comparing the traditional methods.
