Abstract:
In this paper, a three-phase five-level voltage-source inverter is introduced with a new configuration. The proposed inverter constitutes of a conventional three-phase two-level bridge with three bi-directional switches. A multi-level dc-link using constant dc voltage supply and cascaded half-bridge is associated (linked) in such a way that the proposed inverter gives us the required output voltage levels. For the purpose of increasing the number of voltage levels with optimized number of power electronic components, it is recommended to use different methods to determine the magnitudes of utilized dc voltages. The important frequency staircase modulation method is easily used to generate the suitable switching gate signals. Moreover, the model type of the advised configuration can be manufactured as the obtained hardware & simulation results ensures its feasibility of the configuration and the compatibility of the modulation technique is precisely noted.
