| Research Abstract |
Flying capacitor multi-level converters are suitable for circuit integration due to their possibility in reduction of size of capacitors. In this research, behavior of the capacitor voltage is analyzed in detail and a method for stabilizing the capacitor voltage is proposed. Furthermore, generation mechanism and guideline for reduction of electromagnetic noise are clarified, and an implementation of gate driver circuit and their floating power supply suitable for the circuit integration are established. Based on these investigations, several prototypes of the flying capacitor multi-level converter have been constructed. The prototypes have achieved higher output power density than state-of-the-art 2-level inverters.
