A primary and at least one backup alternating voltage source are coupled to a common load to provide interrupt free electric current to the load through a simplified interconnecting network. Phase control of all but one of the sources is accomplished by monitoring the phase difference across choke coils coupling the sources to the load.


An interrupt-free power supply comprising at least two AC voltage sources of equal frequency, each having a set of output terminals, at least one of the terminals being grounded; a number of inductors equal to the number of AC voltage sources, each coupling the ungrounded output terminal of a corresponding one of said AC voltage sources to a common load, whereby the power delivered to the common load by each of said AC voltage sources is related to a voltage phase angle across its associated inductor; a number of feedback circuit means equal to the numbe...
