Abstract:

Multilevel inverters have great applications nowadays as one of preferred solutions for medium and high power applications. As one of the most popular hybrid multilevel inverter topologies, the five-level active-neutral-point-clampedinverter combines the features of the conventional flyingcapacitor type and Neutral-Point-Clamped (NPC) type inverter and was commercially used for industrial applications. In orderto further decrease the number of active switches, this paper proposes a five-level five-switch NPC topology, which employs only five active switches and four discrete diodes. The modulation strategy for five-level five-switch NPC inverter is discussed. A4KVA single phase prototype is simulated using the PSPICE software to verify the validity and flexibility of the proposed topology and control method.
