Abstract
A distributed propulsion system includes a first propulsor and a second propulsor, a first generator configured to generate a first AC current, and a second generator configured to generate a second AC current. The system includes a power regulation circuit. The power regulation circuit includes a first current path that includes a first power electronics circuit, a second current path that includes a second power electronics circuit, a third current path that bypasses the first and second power electronics circuits, and a fourth current path that bypasses the first and second power electronics circuits. The power regulation circuit also includes a plurality of switches configured to selectively couple each respective input to a respective selected output to cause a respective current to flow from the respective input to the respective selected output via one of the first current path, second current path, third current path, or fourth current path.
