Patent ID: 7642756

Claim:
An electric power generating system connectable to a power distribution network, in particular a reconfigurable network, said electric power generating system comprising: a number of alternators, each driven by at least one internal combustion engine and generating an alternating output voltage; said engines running at normally different speeds ω 1 , ω 2 , . . . ωn, so that at least the output voltages V(ω 1 ), V(ω 2 ), . . . , V(ωn) of two different alternators have different frequencies; a number of rectifiers, each of which receives a respective alternating output voltage V(ω 1 ), V(ω 2 ), . . . , V(ωn), and generates a rectified voltage V(r 1 ), V(r 2 ), . . . , V(rn); closed-loop control means, which determine the rectified voltage at the output of each rectifier, and act in negative feedback manner to keep the output voltage V(r 1 ), V(r 2 ), . . . , V(rn) equal to a common target value, so that all the rectified output voltages are substantially equal; and adding means which feed the rectified output voltages to a common node defining an output of the electric power generating system.
