Abstract

The power supply system for controlling supply of power to several inductive loads 101 to 106, 201 to 206 has a power monitor 31, 32 and a processor 3 that determines when power consumed exceeds the capacity supplied by a.c. generators 10, 20. When overload is detected, rapidly disconnects loads of low priority. A software register in the processor is loaded with software controlling staggered reconnection of the loads when power capacity becomes sufficient again. If capacity is sufficient, all the loads may be reconnected together. The system may be used in an aircraft. <IMAGE>
