AC Voltage Sensorless-Based Natural Frame Control of Cascaded H-Bridge Converter Based on Virtual Flux Observer
In this study, a novel natural frame control method without AC voltage sensors is proposed for single-phase cascaded H-bridge (CHB) multilevel converter and implemented in the three-cell CHB converter platform. An improved virtual flux observer (VFO) is introduced to convert the estimated AC voltage...
