Auxiliary power supply for solid state transformers

This paper discusses different ways to obtain an auxiliary power supply (APS) to a solid state transformer (SST) that utilizes the modular AC-DC-DC-AC configuration. A local distributed source, that consists of two APS per module, one for medium voltage (MV) side and another one for low voltage (LV)...

Description
Summary:	This paper discusses different ways to obtain an auxiliary power supply (APS) to a solid state transformer (SST) that utilizes the modular AC-DC-DC-AC configuration. A local distributed source, that consists of two APS per module, one for medium voltage (MV) side and another one for low voltage (LV) side is proposed. For the MV side the use of a high-voltage gain static converter is necessary while for the LV side a commonly static converter may be used. Power factor correction converter is used to supply the main control scheme of SST. All APS systems employed in the SST will described in this paper.
