Virginia Polytechnic Institute & State University will develop a GaN- and SiC-based, utility scale, high power (100 kW), multilevel, medium voltage DC-to-AC inverter that can receive power from sources like batteries or solar panels and transfer it directly to the medium voltage level of the utility grid. The team will also integrate the developed inverter with an existing medium voltage AC-to-DC converter to build a bidirectional solid-state transformer that converts low-voltage AC to high-voltage AC without using heavy, low-frequency materials such as copper and iron in its design. If successful, the project could lead to the first commercially viable medium voltage solid-state transformer, using just a single-stage process to obtain ultra-high efficiency power conversion.
