Abstract
This article proposes a three-phase five-level switched-capacitor active neutral point clamped converter, which can be characterized by voltage boost ability, low-voltage stress across semiconductor devices, and balance of floating capacitor voltage without any auxiliary circuits and/or sensors. Operating principles and modulation scheme of the proposed converter, as well as a comparative analysis with similar topologies are included. Simulation and experimental results for a three-phase prototype are given to demonstrate the feasibility of the proposed five-level converter.
