Abstract

This paper describes a newly developed soft-switching high-voltage active power filter for urban Maglev system applications. The active filter consists of a flying capacitor-based multilevel converter and a soft-switching circuit with coupled inductors. Various aspects like operation, design, analysis and control are discussed in depth and verified through computerized simulation and experimental results. In addition, the study of voltage balancing provided the fundamental high-level solutions to flying capacitor based multilevel converter and inverter applications without additional passive balancing circuits.
