Modern industrial applications deal with power conversion system with lesser harmonic content for variable voltage and variable frequency application. In this paper, a generalized multilevel inverter has been proposed with nearest level modulation technique. A nine-level asymmetrical inverter of 5 kW has been developed as laboratory prototype and tested with three-phase isolated winding induction...
This paper proposes a model after thorough investigation and modelling of different contemporaries Multilevel Inverters. Proposed model uses 9 MOSFETs, 5 diodes, 6 capacitors and 6 DC sources to produce a stepped output waveform having 13 levels. The proposed model is able to achieve as low THD as 7.3% in the open loop system. Proposed Model provides superior waveform quality by maintaining pristine...
The rapid depreciation of conventional energy source makes the reaschers to find the suitable, reliable and efficient source of energy such as solar, wind and tidal etc. Solar energy is the leader of all available renewable energy sources due to its wide distribution and availability. Power electronics people are working hard to enhance the figure of merit of solar cells to extract maximum amount...
These days, the Hybrid Electric vehicles (HEV) are designed for various requirements with varying topologies and control strategies. Design of the drive train components for the desired performance of the vehicle no longer based on different formulae. Fuel economy and emission have become the basic constraint. Automaker has to take care of the road transport policies also before deciding the sizes...
