Designing and Analysis Multi-level Inverter Capable of Power Factor Control with DC Link Switches

Abstract

Due to the increasing demand on the renewable energysources, grid connected electrical converter systems are getting addition a land additional vital than ever before For grid -connected operation, the electrical converter ought to meet the subsequent requirements. This paper proposes a replacement multi-level electrical convertertopology supported a H-bridge structure with four switchesconnected to the dc-link. supported a POD (Phase opposition disposition) modulation methodology, a replacement PWM methodology thatrequires just one carrier signal is recommended. The switchsequence to balance the electrical device voltage is additionally thought-about. Inaddition to those, the planned topology needs minimumnumber of element count to extend range the amount the quantity} of voltagelevel. operational principle of the planned electrical converter is verified through simulation and experiment
