Fuzzy Logic Controller based Hybrid Converter with Simultaneous DC and AC Outputs

Abstract

This Paper introduces new hybrid converter topologies which can supply simultaneously AC as well as DC from a single DC source. The new Hybrid Converter is derived from the single switch controlled Boost converter by replacing the controlled switch with voltage source inverter (VSI). This new hybrid converter has the advantages like reduced number of switches as compared with conventional design and provides DC as well as AC outputs with an increased reliability resulting from the inherent shoot through protection in the inverter stage. The hybrid grid reduces the process of multiple dc-ac-dc or ac-dc-ac conversions in an individual grid where the number of converter stations for converting ac to dc or dc to ac power is reduced. This hybrid can operate in both grid connected and autonomous mode. The proposed grid can operate in both standalone and grid connected mode. Fuzzy controller is used for smooth power transfer.
