Summary:This paper proposes a new isolated multi transformer cell inverter employing low-frequency single-phase transformers and two DC voltage sources. This inverter includes several transformer cells Some of cells contain two unidirectional switches that generate two voltage levels and only one of cells has six switches that provide five voltage levels. Also, the multi transformer cell inverter provides a high number of output levels, symmetric and asymmetric states, reduction of DC sources and high modularity. The operation and performance of the suggested inverter has been proved by simulation and experimental results.
