Abstract: A high power generation system for aircraft includes: a non-propulsive mechanical power source turning a permanent magnet generator (PMG) to generate AC electrical power; a high voltage rectifier unit (HVRU) converting the AC electrical power to DC electrical power, and a control unit controlling the rotational speed of the non-propulsive mechanical power source and the HVRU, wherein the HVRU is configured to increase voltage and current of the DC electrical power using at least one winding of the PMG.

Abstract: A power distribution system for a DC network, the DC network comprising electrical loads, the power distribution system being boarded on an aircraft and comprising: a plurality of AC/DC converters, and at least one AC power source. The power distribution system comprises: an “n” number of AC/DC converters, each one comprising an “(n?1)” number of first outputs and at least an additional output, and an “(n?1)·n” number of electrical loads. Each electrical load comprises two inputs: a first input for being connected with a corresponding first output, and a second input for being connected with any of the additional outputs. The power distribution system is configured to continue supplying electrical power to the DC network in case an AC/DC converter is not energized, such that the second input of such electrical load is connected to any additional output of another AC/DC converter, being the first input disconnected.
