Fuzzy Based Phase-Shift PWM Controller for Four Level Hybrid Converter

Abstract

This paper introduces an advanced four-level hybrid converter topology which is made out of eight switches and one flying capacitor per stage. The working standard is presented and stage moved heartbeat width balance is utilized to control this converter. A detailed examination of the normal streams through the flying capacitor and unbiased purposes of the dc-interface is displayed. In view of the examination, it can be inferred that the voltages over the flying capacitor and dc-connect capacitors can be normally adjusted under perfect and unfaltering state condition. Simulation model is developed to approve the proposed topology and modulation technique.
