Electric vehicles (EVs) are believed as efficient solutions to reduce carbon emissions and
fossil fuel reliance in transportation sectors. Yet, the ever-increasing penetration of EVs also …

Cascaded-bridge converters (CBCs) and modular multilevel converters (MMCs) enjoy
growing popularity mostly due to modularity and scalability. Conventionally, their …

The nonresonant single-phase dual-active-bridge (NSDAB) dc-dc converter has been
increasingly adopted for isolated dc-dc power conversion systems. Over the past few years …

High-frequency-link (HFL) power conversion systems (PCSs) are attracting more and more
attentions in academia and industry for high power density, reduced weight, and low noise …

This paper introduces a new module for asymmetrical multilevel inverters with a low number
of components. The module is a square combination of two back-to-back T-type inverters …

Microgrids have been widely studied in the literature as a possible approach for the
integration of distributed energy sources with energy storage systems in the electric network …

The solid-state transformer (SST) is an interface device between ac distribution grids and dc
distribution systems. The SST consists of a cascaded multilevel ac/dc rectifier stage, a dual …

Full-order continuous-time average modeling and dynamic analysis of bidirectional dc-dc
dual active bridge (DAB) converters are studied. The transformer current in DAB converter is …

Dual active bridge (DAB) dc-dc converters have several attractive features including auto-
adjust bidirectional power flow, wide voltage gain range, and zero voltage switching (ZVS) …

Solid-state transformer (SST) has been regarded as one of the most important emerging
technologies for traction system and smart grid application. This paper presents the system …
