Design and Analysis of Hybrid Multilevel Inverter for Asymmetrical Input Voltages
Dwivedi Arpan,Pahariya Yogesh 대한전기학회 2021 Journal of Electrical Engineering & Technology Vol.16 No.6
The conversion of DC to AC has emerged as a vital role in Standalone power supply system. While converting DC to AC, it is conceivable to acquire the preferred output voltage and frequency. Voltage source inverters are basically categorized on the basis of output voltage waveforms. Multilevel inverters are replacing conventional inverters by overcoming the short coming of classical topologies. In practical implementation of conversion factors that should be considered are reducing component count and performance characteristics like fault tolerance capability, charge balance control, etc. This paper deals with the design of the single phase hybrid multilevel inverter using the Three-level diode clamped leg and Three-level T-type leg using asymmetrical voltage input sources for standalone system. The entire mathematical modeling of proposed hybrid inverter is presented. The performance parameters evaluated for asymmetrical source condition are THD analysis, reliability, switching and conduction losses are carried out. The simulation and hardware implementation of proposed topology at same load conditions has been done; both the hardware and simulation results are compared.
