A reliable and redundant hybrid VTOL UAV power architecture includes two or more channels of high voltage AC power generated from at least one generator, the generator coupled to one or more liquid fueled turbine engines. Two or more high voltage domain modules, one for each channel, receive the high voltage AC power and, using a rectifier change it to high voltage DC power. A power distribution unit accepts the newly converted channel of high voltage DC power and thereafter bidirectionally provides it to a domain battery and to a primary set of motors. Two or more high voltage busses, each coupled separately to one of the two or more high voltage domain modules, each redundantly transport converted channel of high voltage DC power to, in one embodiment, primary sets of motors forming a primary high power domain bus for these select motors.
