Summary:This paper proposes a new structure of DC-AC multilevel converters which is developed by combining a modification of a DC-DC buck converter and a DC-AC hybrid multilevel converter with cascade configuration and a ratio of 1:1.5. The buck converter is used to obtain two independent voltage sources from a single power supply without using transformer. The advantages of this configuration are: it does not require isolated power supplies and has a high power density because it does not use transformers.
