This paper focuses on an implementation of new topology which can synthe-size multi-level output voltage at the load terminals. The proposed inverter consists of two main parts; level generation part and polarity generation part. Level generation part is responsible for generating voltage levels at its end while; polarity generation part is a traditional H-bridge which is used to provide inversion of the output voltage levels. Single-phase seven-level inverter has been presented from the proposed multilevel inverter. This topology offers reduced number of switching components compared with many recent availa-ble topologies particularly for high number of levels. Due to the multi-level output voltage, low total harmonic distortion (THD), less circuit complexity, less cost and high efficiency can be obtained. A conventional PI controller is used for load voltage regulation to obtain output voltage near to sinusoidal. Computer-aided using the dSPACE_CP1103 controller and experimental setup are carried out to provide the validity and effectiveness of the proposed invert-er.
