Abstract: A power conversion system includes one or more solid state transformers, and a medium voltage DC-AC inverter. Each solid state transformer includes a primary stage, including at least one DC-AC converter, each arranged to receive low voltage DC power from a power generation unit, and one or more primary medium frequency transformer windings, and a secondary stage, including at least one AC-DC rectifier, each arranged to receive AC power from a respective secondary medium frequency transformer winding. The medium voltage DC-AC inverter is configured to receive medium voltage DC power from one or more rectifiers and output medium voltage AC power.
