AN ELECTRICAL POWER SUPPLY DEVICE FOR POWERING AT LEAST ONE PIECE OF EQUIPMENT OF AN AIRCRAFT ROTOR, AND AN AIRCRAFT

摘要

The present invention relates to a power supply device (10) containing a pole (11). The pole (11) includes a rotary casing (12), which is equipped with a fastener unit (14) to fasten the rotary casing to a mast, and a non-rotary casing (15). The pole (11) is fixed to the non-rotary casing (15) and includes a non-rotary converter (20) which generates alternating current at a frequency higher than 1 kHz. The pole also includes a rotary converter (25) which is equipped with a primary component (26) fixed to the non-rotary casing (15) and a secondary component (27) fixed to the rotary casing (12). The primary component (26) is connected to the non-rotary converter (20) to receive the alternating current. The secondary component (27) is suitable for a power supply apparatus (100) of a rotor (2).
