Novel Multilevel Inverter using a Single H-Bridge

A novel (N+1)-level multilevel inverter (MLI) using a modified solar panel (MSP) and newly proposed commutator coupled with slip rings, is presented in this paper. This multilevel inverter has only one H-bridge (HB) unit. The number of voltage levels of MLI depends on the number of the output terminal of MSP. The sinewave output is made possible by two-dimensional controls. The staircase sine wave has been converted into pure sinewave by using the filter capacitor at H-bridge. It is transformed to high voltage sinewave by using a step-up transformer. This proposed technique is verified by simulation and prototype.
