摘要

The circuit has a power distribution system (17) provided at an aircraft, and another power distribution system (25) integrated to an engine (23) of the aircraft. Electrical equipments such as de-icing system (5a), engine loads (5b) and nacelle loads (5c), are connected to one of the distribution systems for receiving an alternating voltage. A power supply device includes two inputs respectively connected to the distribution systems for receiving the alternating voltage.
