| Abstract |
This paper presents a circuit configuration of multilevel inverter to synthesize a large number of output voltage levels by connecting a full-bridge inverter to a 5-level inverter in series. We analyze the characteristics by computer-aided simulations and experiments when it has input voltage sources which have the same and the power of three in the amplitude. In addition, it is compared with the conventional transformer based multilevel inverter. |
