This paper presents a novel interleaved high-conversion-ratio bidirectional DC-DC
converter based on switched capacitors and coupled inductors. Series-connected switched …

Increase in global energy demand and constraints from fossil fuels have encouraged a
growing share of renewable energy resources in the utility grid. Accordingly, an increased …

Solid-state-transformer technology pushes the specifications of electric transformers in the
high-power medium-frequency range. This combination results in larger-sized transformers …

Solid-state transformers (SST) are emerging technologies to replace the conventional low-
frequency main transformer (MTR) in railway vehicles. In order to isolate the load side from …

Medium-voltage (MV) dual-active-bridge (DAB) converters have become an emerging
technology thanks to high-voltage silicon carbide (SiC) devices and nanocrystalline …

High-voltage (HV) wide bandgap (WBG) silicon carbide (SiC) power modules, capable of
higher switching frequencies and thermal stresses than their silicon-based counterparts, are …

Multiple topologies of solid-state transformers (SST) were proposed for locomotive traction
systems, and more recently, for electric power distribution systems because of advantages …

This paper targets photovoltaic microinverters (MIVs) with integrated battery storage. The
dual-active-bridge (DAB) topology provides bidirectional power flow; however, it generally …

The objectives of this paper are to review and compare the design of high-frequency
transformers (HFTs) for low-power solid-state transformer (SST) converter topologies. Two …

This paper presents the analysis of the current resonances on medium-voltage, medium-
frequency transformers due to the parasitic capacitances of the windings. Converter …
