FIELD: electric engineering, possible use for engineering systems for supplying electricity to functional units of aircrafts.
SUBSTANCE: device is made in form of two electric channels for supplying high alternating current voltage to consumers. Each channel includes alternating current generator 3 (4), mounted on the shaft of aircraft engine 1(2), output of generator is connected to input of main controllable rectifier 5 (6) and to input of additional controllable rectifier 14 (13) of opposite channel, output of which is connected to input of corresponding controllable inverter 7 (8). On failure of aircraft engine of one of channels, provision of electric power to electric power consumers occurs from alternating current generator of opposite channel. When aircraft engine operates in auto-rotation mode, on output contacts of main rectifier of that channel emergency low constant current voltage ±27V is created.
EFFECT: increased reliability of uninterrupted provision of energy to consumers in form of high alternating current voltage.
