Title:
POWER DISTRIBUTION SYSTEM AND POWER DISTRIBUTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/039475
Kind Code:
A1
Abstract:
A power distribution system 100 is installed in an aircraft, and comprises: a first DC power source unit 10 including a generator 11; a second DC power source unit 20 including a battery 30, a step-up/down converter 41, a voltage sensor 43, and a control unit 44; and a diode 50. When the voltage sensor 43 does not detect regenerative power, the control unit 44 executes a running power processing mode in which generated power generated by the first DC power source unit 10 is supplied to an electric actuator 80 while charging and discharging the battery 30 using the step-up/down converter 41 so as to keep a charge rate A of the battery 30 within a predetermined range. When the voltage sensor 43 detects regenerative power, the control unit 44 executes a regenerative power processing mode in which the battery 30 is charged with the regenerative power using the step-up/down converter 41.
