Multi-winding transformer based diode-clamped multi-level inverter

In this paper, a new configuration for diode-clamped multilevel inverter based on multi-winding transformer is proposed, described and simulated. The most important difference between this proposed DC-AC-AC structure and basic structure is that in the proposed structure, back-to-back connected outputs of a multi-winding transformer are superseded the capacitors in basic structure. Simulation a 7 levels of proposed configuration shows 10% THD.
