Electrically driven distributed propulsion system

A hybrid propulsion system, comprising:

• a starter generator configured to provide AC power to a first bus and a first inverter;
• a second inverter electrically coupled to the first inverter;
• a first switch configured to selectively couple the second inverter to the first bus when in a first position and to a second bus when in a second position;
• a second switch configured to selectively couple a first motor to the first bus when in a first position and to the second bus when in a second position;
• and
• a controller electrically coupled to the second inverter, the first switch, and the second switch, wherein the controller is configured to:
• set the first switch to the second position and the second switch to the second position, wherein the first motor is electrically coupled with the second inverter and the starter generator via the second bus,
• cause the second inverter to convert the AC power received from the first inverter to a starting AC power for starting the first motor,
• cause the second inverter to increase the starting AC power to match the AC power provided to the first bus from the starter generator, and
• switch the second switch to the first position, when the starting AC power matches the AC power provided to the first bus from the starter generator.
