Switch-ladder: reliable and efficient multilevel inverter
Esfandiari, Ehsan and Mariun, Norman and Marhaban, Mohd Hamiruce and Zakaria, Azmi (2010) Switch-ladder: reliable and efficient multilevel inverter. Electronics Letters, 46 (9). pp. 646-647. ISSN 0013-5194
A DC-AC-AC multilevel inverter based on a multi-winding transformer is presented. The most important advantage of this inverter is that only four switches conduct during each cycle, which means that it exhibits lower on-state power dissipation. High reliability when switches fail in open-circuit behaviour is another advantage of this inverter structure. Finally, practical results are presented.
