Redundant power distribution circuits including dc/dc converters

An electrically powered vehicle comprising:

• a plurality of batteries;
• a plurality of DC to DC converters, each coupled to a respective battery of the plurality of batteries and configured to generate DC power that is coupled to a common DC bus;
• a plurality of inverter circuits coupled to the common DC bus;
• and
• a plurality of electric motors each coupled to a respective inverter circuit of the plurality of inverter circuits, wherein each motor of the plurality of electric motors propels the vehicle.

A circuit comprising:

• a first battery coupled to a first DC to DC converter;
• a second battery coupled to a second DC to DC converter;
• a DC bus coupled in parallel to the first and the second DC to DC converters;
• a first inverter coupled to the DC bus;
• a second inverter coupled to the DC bus;
• a first motor coupled to the first inverter;
• and
• a second motor coupled to the second inverter.
