An electrical power distribution system for converting and distributing electrical power to local loads within a vehicle is disclosed. The electrical power distribution system includes at least one generator providing high voltage AC (HVAC) power, a primary power panel for receiving the HVAC power from the generator, and a plurality of distribution conversion units located throughout the vehicle. The plurality of distribution conversion units convert the HVAC power from the primary power panel into medium voltage AC (MVAC) power and low voltage DC (LVDC) power for consumption by the local loads within the vehicle. The electrical power distribution system also includes a plurality of HVAC distribution feeder lines. Each HVAC distribution feeder line connects the primary power panel to one of the plurality of distribution conversion units.
