Descrição
Resumo:A three-level common-mode voltage eliminated in- verter with single dc supply using flying capacitor inverter and cascaded H-bridge has been proposed in this paper. The three phase space vector polygon formed by this configuration and the polygon formed by the common-mode eliminated states have been discussed. The entire system is simulated in Simulink and the re- sults are experimentally verified. This system has an advantage that if one of devices in the H-bridge fails, the system can still be oper- ated as a normal three-level inverter at full power. This inverter has many other advantages like use of single dc supply, making it pos- sible for a back-to-back grid-tied converter application, improved reliability, etc.
