In this work, a transformerless DC/DC converter is presented with dual operating modes buck–boost procedure. As simple structure and continuous input current port, the system acts as common ground between output terminal. One mode, quadratic voltage gain ratio D/(1-D)2, other mode D/(1-D). present study, conduction (CCM), steady-state conditions were assumed to analyze efficiency small-signal m...

MMC is a promising technology for MTDC systems and would transform into the concept of Supergrids in near future. The salient features are modularity, reduced dv/dt di/dt stress on switches, voltage power scalability, inherent fault blocking capacity, transformerless operation, improved quality. However, there some technical issues challenges to be critically analysed addressed. There room deve...

HIGHLIGHTS Single-switch configuration for the proposed hybrid converter is employed. Static voltage gain of topology improved. Power switch subjected to low voltage-current stress. The power conversion efficiency

This paper proposes a high voltage gain dc/dc converter with coupled inductor cells and switched capacitor for renewable energy applications. It includes coupled inductor, switched capacitor and voltage multiplier cell. Switched capacitor charged during off period by using the energy stored in the coupled inductor. This will increase the performance of the converter. The voltage gain of traditi...
