Abstract
The paper presents an analysis of a novel cascaded multilevel inverter, which consists of two cascaded bridges per phase. The upper bridge produces 5-level voltage and consists of only two bi-directional and four standard IGBT switches in each 5-level H-bridge. The lower bridge is standard 3-level Hbridge. The inverter is controlled by Phase Disposition (PD), Phase Opposition Disposition (POD) and Alternative Phase Opposition Disposition (APOD) PWM methods. The significant advantages of the proposed inverter are simpler control and lower number of components such as switches, diodes and capacitors than in the standard multilevel topologies. Extensive simulation results validate the practicability of the proposed inverter. The proposed topology can be extended to any desired number of levels by cascading additional bridges.
