Abstract:
1. A system for generating electric power, comprising: an electric-power source, having a preferential point of operation, correlated to at least one variable parameter that can vary as a function of at least one non-controllable event; a double-stage inverter having an output coupled to an electrical power network and further comprising as a first stage a DC/DC boost converter, controlled via a control parameter, and as a second stage a DC/AC inverter; a block for identifying the preferential point of operation, said block supplying a reference signal according to the conditions of operation of said electric-power source and to the preferential point of operation of said electric-power source; a corrector block comprising a compensator effective to set the control parameter for the boost converter as a function of an error signal generated by a comparison of said reference signal and a signal of actual operation of said electric-power source, wherein said electric-power source is maintained in the proximity of the preferential point of operation; and the boost converter effective in response to the control parameter to suppress or reduce an effect on said reference signal and said variable parameter of at least one disturbance at a pre-determined frequency coming from the electrical network to which the output of said inverter is connected.
