Improving micro-grid management: A review of integration of supercapacitor across different operating modes.

The field of electrical energy is moving through many rapid changes and continuous development, especially with the huge boom in the field of artificial intelligence (AI) and the presence of renewable energy systems (RESs). Simultaneously with this development, it was necessary to have energy storage systems such as super capacitors and batteries. This necessity increased with sudden changes in climate or loads that affect the output of generation systems such as solar and wind energy systems.

High gain DC/DC converter with continuous input current for renewable energy applications.

In this paper, a new design of a non-isolated high-voltage gain DC/DC converter that operates at a reasonable duty cycle, by merging the dual boost converter with the switched inductor structure, is presented as a solution for the high-conversion ratio requirement. The proposed converter operates in discontinuous-current mode (DCM) with zero current switching for all switches and diodes. Wide duty cycle range operation, high output voltage gain, low switching stress, small switching losses, and high efficiency are achieved efficiently.
