A novel high-conversion-ratio bidirectional three-phase DC–DC converter
A novel high-conversion-ratio bidirectional three-phase DC–DC converter is proposed in this paper, which features not only low switch voltage and current stresses, but also automatic voltage balancing and current sharing ability without adding extra ...

Hybrid AC‐DC microgrids (HMGs) are formed by interconnecting AC microgrids (MGs) and DC microgrids via AC‐DC interlinking converters (ICs). In the islanded mode, apart from power sharing in a single MG, power sharing expansion throughout HMG is desirable.

Capacitor voltage balancing control with reducing the average switching frequency in MMC
Modular multilevel converter (MMC) has a very good application prospect in the flexible high-voltage direct current (HVDC) transmission, but higher self-loss will affect the efficiency and restrict the development.

Josephson and Persistent Spin Currents in Bose-Einstein Condensates of Magnons
Using the Aharonov-Casher (A-C) phase, we present a microscopic theory of the Josephson and persistent spin currents in quasi-equilibrium Bose-Einstein condensates (BECs) of magnons in ferromagnetic insulators. Starting from a microscopic spin model that

Effect of spin rotation coupling on spin transport
We have studied the spin rotation coupling(SRC) as an ingredient to explain different spin related issues. This special kind of coupling can play the role of a Dresselhaus like coupling in certain conditions.

Decentralised control and fault ride-through of a multi-microgrid system
A multi-microgrid (MMG) system comprises of a cluster of microgrids interconnected for reliable and efficient operation in grid connected as well as islanded modes. In this study, the fault-ride-through capability of an MMG system is addressed.
