A Compact Auxiliary Power Supply Design for a Medium Frequency Solid State Transformer

IEEE Transactions on Transportation Electrification, 2023
The design of auxiliary power supply (APS) in solid-state transformers (SSTs) is quite challenging. To minimize the isolation requirement, this APS is usually powered by dc-link capacitors.

Virtual Transformer Operation of Solid State Transformer (SST)

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
This paper proposes a virtual transformer operation of a three-stage solid state transformer (SST) used in the distribution network. By tracking the AC voltage at medium voltage AC (MVAC) input side as the reference of low voltage AC (LVAC) output stage, voltage relationship between AC buses can be established, and the mutual voltage support can be ...

Analysis of a Solid-State Transformer Employing Capacitively Isolated Series-Stacked Converter Cells and a Single Medium-Frequency Transformer

Compel, 2023
Solid-state transformers (SST) provide voltage scaling and galvanic isolation between medium-voltage (MV) and low-voltage (LV) dc busses. Most SST topologies arrange several isolated dc-dc converter cells in an input-series, output-parallel (ISOP ...
