Implementation of a new Bi-Directional Switch multilevel Inverter for the reduction of harmonics

Abstract

Abstract In the current scenario, multilevel inverter plays a major role in heavy duty drive systems. MLI is one of the most advanced power converters for highly efficient AC output. But there is more to the requirement of number of control switches and total number of input sources which often generates more losses. This paper presents a new multilevel inverter design with limited number of control switches and with just one DC source to reduce these demerits. It uses a smaller number of Bi-directional switches. So that complexity of the circuit is reduced. Finally, an eleven-level inverter is designed and simulated using MATLAB/SIMULINK and THD reduction has been analyzed. This paper also provides a comparative statement of required components for various conventional methods.
