A 13.2kV / 150kVA Solid State Transformer for a Bipolar LVDC Distribution System

In this paper, in order to supply a bipolar ± 750 V
_DC
for LVDC distribution system, a 13.2kV
_AC
/ 150kVA solid state transformer (SST) was proposed. This prototype SST was installed in Go-Chang which is DC distribution test site in Korea. The design and performance of the proposed SST are verified by experimental results using a 150kVA prototype.
