Abstract 

This is a multi-winding transformer insulation test for the auxiliary power supply of solid state transformers. The multi-winding transformer consists of two UU80 cores. 7 PCB-based MV-side windings are placed within the epoxy layer. A 50-Hz AC voltage with an RMS value of 20 kV was applied between the MV-side and LV-side of the transformer. The insulation of the transformer performed well.
