Patent number: 11715948Abstract: A vehicle is provided that includes a basic structure; and coupled to the basic structure, power sources, a propulsion system and power distribution circuitry. The propulsion system includes a plurality of electric motors configured to power propulsors to generate propulsive forces that cause the vehicle to move. The power distribution circuitry is configured to deliver DC electric power from the power sources to the electric motors, the power distribution circuitry including a plurality of DC-to-DC converter assemblies configured to input the DC electric power from the power sources and deliver voltage-regulated outputs to the electric motors, a DC-to-DC converter assembly operatively coupled to multiple ones of the power sources and multiple ones of the electric motors, and the DC-to-DC converter assembly including a multiple-input and multiple-output (MIMO) transformer with a single transformer core.Type: GrantFiled: November 18, 2021Date of Patent: August 1, 2023Assignee: THE BOEING COMPANYInventors: James Perkinson, Andrew S. Babel, Robert J. Atmur
