Patent ID: 8174138

Claim:
A modular converter for converting the electric power produced by aerogenerators, for use inside a wind-power plant, comprising: input terminals on said modules and on said converter, configured for being connected to an electric-power generator of a single-phase or multiphase type; output terminals; a first controller for controlling the power of said electric-power generator; a plurality of modules receiving on inputs alternating electric current and to produce on respective outputs direct electric current to be distributed within said wind-power plant, said modules being configured in series to one another, wherein the input terminals of said modules are electrically connected to the input terminals of said converter; a plurality of insulated-gate bipolar transistors inside said modules, each of said transistors comprising a gate terminal, a collector terminal and an emitter terminal; each module comprising a respective secondary controller, configured to interact with said first controller and to keep the direct current voltages of the modules balanced with respect to one another, the secondary controller acting on the gate terminals of each transistor; and wherein said first controller receives a signal from said modules and acts on the electric-power generator.
