Abstract (en)

[origin: FR2766636A1] The invention concerns a converter, powered by an alternating network, taking therefrom a current with a power factor close to one unit and a non-linear distortion factor close to 5 %, whereas the amplitude of the current applied at the output load (2) remains substantially constant. It comprises a bridge structure using switching means (1', 1") and capacitors (3a, 3b) whereof the reactance at the quench frequency is selected such that a portion of the converted energy, after being rectified, is added between the terminals of a capacitor (6) to the mains current rectified by a bridge (7). A buffer source (4) has a direct voltage with substantially constant amplitude, which enables to balance the potentials generated thereby eliminating all risks of destruction by uncontrollable excess voltages.
