Switching Angle Calculation By EP, HEP, HH And FF Methods For Modified 11-Level Cascade H-Bridge Multilevel Inverter
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 12
Abstract
In this paper the switching angles, from that the time required, to generate triggering pulses for IGBT switches of a single-phase Modified 11-Level Cascade H-Bridge Multilevel inverter is described by using Equal Phase (EP),Half Equal Phase (HEP), Half Height (HH) and Feed Forward (FF) methods. The proposed eleven level inverter is based on the H-bridge inverter. Instead of twenty IGBT switches as in conventional Cascade H-Bridge, this inverter requires only nine IGBT switches to obtain eleven level output. Because the numbers of switches are less, the cost and the complexity of the circuit is simple. The simulation results are presented using MATLAB/SIMULINK.
