Single-source binary hybrid multilevel inverters with cascaded transformers have a bulky transformer connected to their main H-bridge cells in each phase. This bulky transformer has been eliminated in this work without any effect on operation and modulation strategies. The proposed topology has significant advantages from view point of dimensions and number of transformers, design of transformers, modeling and application aspects. Modulation strategy of the proposed inverter is the conventional binary hybrid modulation. Simulation and experimental results demonstrate suitable performance of the proposed topology.
