A device for supplying direct current voltage from an imposed alternating current network. The invention relates to an electronic converter which controls the wave form of the input voltage which is identical to that of the input current and controls a controllable direct current at the output thereof . It consists of a rectifier bridge (2) which is supplied by an imposed alternating current (I<SUB>L</SUB>) directly or via a current transformer (1) and which discharges a current (I<SUB>L=</SUB>) via an inductor (3), a diode (4) and an energy storage capacitor (6) in a parallel manner onto the output charge (7). An output voltage (U) controller (14) receives at the input thereof (?) between measurement (u) of the output voltage (U) and the setpoint value (u<SUB>R</SUB>) . An operator (100) divides or multiplies the output signal (i<SUB>L</SUB>) of the translator (9) of the supply current (I<SUB>L=</SUB>) of the converter via the output signal (ß) of the controller (14) . The input voltage controller (11) is controlled by error (?), between the output (?) of the operator (100) and the measurement value (v) obtained at the output of the input voltage transducer (8). The output (R) controls the transistor (5). |
