Abstract Scope |
High power, medium voltage, medium frequency, transformers (MVMFTX) are the principal component that enables solid-state transformer (SST) operation with galvanic isolation. As SST technologies mature, there are new suppliers of commercial MVMFTX prototypes. However, these commercial prototypes are seldom provided with construction details which are essential to understanding the transformer performance and behavior. Furthermore, these details may be protected intellectual property, making the MVMFTX a proverbial black box. Proper design and operation of SSTs need accurate models of the transformer to understand basic issues as losses, saturation, common-mode impedance. In this presentation, we will describe and show a sufficient characterization process with LCR meters and an MV characterization circuit to capture the small and large signal behavior of the MVMFTX. We will identify critical construction and material properties. Furthermore, the application relevant MVMFTX material characterization can validate of requested specifications and define critical operational bounds for MV SST performance. |
