Now-a-days, non-conventional energy sources are playing a vital role in the generation of electrical energy. This is due to disadvantages conventional like pollution, non-availability resources, greenhouse effect. Hence more concentration made by researcher’s on these so called as renewable sources. These used with converters along filters give best output. In this work, we focusing solar and h...

This paper used an artificial jellyfish search (AJFS) optimizer suitable for selective harmonic elimination-based modulation multilevel inverter (MLI) voltage control application. The main objective was to remove the undesired lower-order harmonics in output waveform of MLI. algorithm motivated by behavior ocean. Jellyfish have ability find global best position where a large quantity nutritious...

Abstract— In this research, a single phase Z-source cascading Multilevel Inverter, Nine-level inverter topologies with a trinary DC sources are offered. The recommended topologies are expanded by cascading a full bridge inverter with dissimilar DC sources. This paper recommends advanced pulse with modulation technique as a switching scheme. In this PWM technology, trapezoidal modulation techniq...

The output voltage of a Multilevel Inverter (MLI) can be controlled using various low and high frequency modulation strategy. Apart from meeting the load demand, strategy also tries to reduce harmonics present in waveform. In this paper, novel strategy, Variable Structure Nearest Level Modulation (VSNLM) has been proposed with objective Total Harmonic Distortion (THD) thus giving better quality...

Cascaded H-bridge multilevel power electronic converters generally require several dc sources. An alternative option is to replace all the separate dc sources feeding the H-bridge cells with capacitors, leaving only one H-bridge cell with a real dc voltage source. This will yield a cost-effective converter. However, the required capacitor voltage balancing is challenging. In this paper, using t...
