Comparative Analysis of Cascaded H- Bridge Inverter and RV Inverter Topology
Abstract: This paper presents a comparative analysis of seven levels Cascaded-H-bridge inverter and RV topology based on SPWM control techniques. Three distinctive major multilevel inverter is flying capacitor multilevel inverter, diode clamped multilevel inverter and cascaded multilevel inverter have been used in industrial application among them cascaded H-bridge multilevel inverter has more advantages compared to other two multilevel inverters as it requires less number of components and no voltage balancing problem. The main drawback of cascaded multilevel inverter is it requires isolated DC sources, increased number of components, complex firing method mainly used SPWM method which requires m-1 carrier signal for firing the power electronic switches which increases the complexity. In this paper, a new inverter topology with a reversing-voltage topology is compared with conventional cascaded H- bridge multilevel inverter to improve the multilevel performance. RV topology requires fewer components compared to existing inverter as RV topology requires less number of switches which reduce the number of gate drive circuit. Also a less number of the carrier signal is used in RV topology because this topology generates only positive cycle. Therefore, the overall cost and complexity are greatly reduced, particularly for higher output voltage levels.
