High voltage power switches are needed for medium-voltage (MV) grid applications such as
Solid-state Transformers. The series-connection of low voltage devices is a cost-effective …

This paper proposes a novel medium voltage (MV) solid state transformer (SST) based DC
fast charger (SST-DCFC). The SST-DCFC utilizes a patent pending AC/DC topology which …

Soft-switching technique has potential to be used in solid-state transformers (SSTs) to
increase the efficiency and power density. In conventional two-stage SST modules, the first …

Class 2 transformers are small line-frequency transformers widely used for control systems
requiring 24 VAC signaling, including residential and commercial HVAC systems, industrial …

In a solid-state transformer (SST), the transformer with high insulation voltage is one of the
most important components. The PCB-winding transformer is one promising candidate …

Low-power line-frequency transformers are common across several applications, but these
transformers are found to have large standby losses, low efficiencies, large weights, and …

This paper presents a current and voltage-balance control strategy for a 1MVA/4.16 kV
modular, single-stage, PV plus Storage Solid State Transformer (PVS-SST). The PVS-SST …

Hybrid Solid State Transformers (HSSTs) are systems comprising of a fractional power solid-
state transformer (SST) integrated with a standard full power line frequency transformer …

The paper evaluates various solid-state transformer (SST) topologies and selects the Type E
architecture with three-stage conversion. This architecture includes medium-voltage DC …
