Abstract

Abstract: The employing of power electronic devices for converters plays a vital role in the conversion of AC to DC vice versa. Applications of these converters more demand in renewable energy, hybrid vehicles, Drives, HVDC, etc. In renewable energy, especially a solar-based power generation stations require inverter stations. These inverters stations have the multilevel inverters. Multilevel inverters are emerging day by day in the sector of the renewable energy sector. The increasing level of multilevel inverters can be effectively utilized in low and medium voltage applications to get the desired voltage and frequency. But output voltage is not in sinusoidal. However, most of the loads require a pure sinusoidal form of voltage. To get sinusoidal voltage across loads a high switching frequency is required to switch the MOSFETs or IGBTs. Along with a suitable value of LC, filters make the sinusoidal nature of waveform with less total harmonic distortion (THD) levels. To get a sinusoidal wave, a proper theoretical analysis of filters is required. In this paper theoretical analysis has been done for LC filters and checked with simulation results for various loads. The performance of theoretical LC filters values checked using diode clamped multi-level inverters have been examined through MATLAB/SIMULINK by POD PWM by POD PWM.
