Patent ID: 8487560

Claim:
An electric brake system for an electromechanical machine connected to output terminals of an inverter, wherein input terminals are supplied by a DC voltage source, the system comprising: an electrical circuit connected between the input terminals of the inverter and comprising, connected in series: means for dissipating electrical energy returned by the electromechanical machine to the input terminals of the inverter during a braking phase of the electromechanical machine; switching means for closing the electrical circuit during a braking phase of the electromechanical machine and for opening the electrical circuit in absence of a braking phase of the electromechanical machine; wherein the means for dissipating the electrical energy comprises an inductor wound around a magnetic circuit, energy recovered by the inductor during the braking phase being dissipated by loss of hysteresis and eddy currents in the magnetic circuit; a differential mode filter comprising a filtering inductor, wound around a magnetic circuit placed in series between the DC voltage source and the inverter; and a filtering capacitor placed between the input terminals of the inverter, the filtering inductor and the dissipation inductor have a shared magnetic circuit.
