Özet

In this paper, a novel topology for single-phase 7-Level inverter is introduced. Structural parts of the inverter are described in detail. Switching strategy and operational principles of the proposed inverter are explained and operational topologies are respectively given. A method and a formula are improved for calculating switching angles. The validity of the proposed inverter is verified through simulations. Simulation results are given and compared with conventional H-Bridge Inverter. Simulations for 15-Level and 31-Level inverters are also performed for comparison and improving proposed inverter for the future work. A prototype of the proposed inverter is manufactured and experimental studies are realized. The proposed inverter generates a high-quality output voltage wave form. It reduces dv/dt stresses imposed on power-switching devices and also harmonic components of output voltage and load current quite well.
