This paper proposes a new bidirectional DC/DC converter for supercapacitor applications. The proposed converter has a parallel structure in supercapacitor side (where voltage is low and current is high) and a series structure in the other side. This structure increases efficiency of the converter. For current sharing in the parallel side of the proposed converter, two different methods are reco...

Load balancing is an important issue in distributed systems. In addition, using distributed generation sources such as photovoltaic is increasing. Power electronic converters are main interfaces between the sources and the grid. In this paper, a method has been proposed to reduce the load imbalancing in distribution networks using PV Grid Interface Converter. Two DC/DC and DC/AC converters have...

Input-series-output-parallel (ISOP) isolated bidirectional DC/DC converter (IBDC) become a preferred scheme connecting high-voltage and low-voltage bus in DC distribution network. Input-voltage-sharing (IVS) among modules is essential to realize the stable operation of ISOP system. Nowadays, with large-scale access distributed energy sources loads grids, fluctuations voltage connected load freq...

The transportation industry is transitioning from conventional Internal Combustion Engine Vehicles (ICVs) to Electric (EVs) due the depletion of fossil fuels and rise in non-traditional energy sources. EVs are emerging as new leaders industry. Some essential requirements necessary for widespread adoption include sufficient charging stations with numerous chargers, less no wait time before charg...

The idea of a microgrid is created by utilizing more diverse ac or dc distributed generation (DG) sources along with an energy storage system (ESS) and loads. The most efficient and reliable selection of ac and dc microgrids is a hybrid ac/dc microgrid. The hybrid microgrid largely overcomes the shortcomings of standalone ac or dc microgrids. A bidirectional interlinking converter (BIC) is util...

Multiport converters are used in interfacing of distributed energy sources with grid/load. Isolated needed applications where converter gain is high and there a requirement isolation. Dual transformer asymmetric triple active bridge offers the advantage reduced circulating current. However, operating range low for variation load source voltage. In this paper duty ratio modulation technique prop...
