Abstract
Circuit pour produire, transférer entre des circuits de tension différente et stabiliser un courant alternatif, comportant un échantillonneur (2) doté d'une entrée de synchronisation (4) et d'une entrée de régulation (3), un détecteur de courant (5), un circuit de filtre (6), un inverseur (7) auto-hétérodyne produisant une tension carrée et doté d'une sortie de signal synchrone (8) et un circuit de réglage (9). La caractéristique de la présente invention est qu'une tension continue (1) se modifiant dans des limites déterminées est appliquée via l'échantillonneur (2), le détecteur de courant (5) et le circuit de filtre (6) à une entrée de l'inverseur auto-hétérodyne (7) dont la sortie de signal synchrone (8) est amenée à l'entrée de synchronisation (4) de l'échantillonneur (2). Une sortie (13) du détecteur de courant (5) fournissant un signal proportionnel à la moyenne de courant se raccorde à une entrée (10) du circuit de réglage (9), alors qu'un signal de référence (14) déterminant la valeur du courant est amené à l'autre entrée du circuit de réglage (9). La sortie du circuit de réglage (9) est reliée à l'entrée de régulation (3) de l'échantillonneur (2). La sortie de l'inverseur (7) forme simultanément la sortie de courant alternatif du circuit.Circuit for producing, transferring between circuits of different voltage and stabilizing an alternating current, comprising a sampler (2) provided with a synchronization input (4) and a regulation input (3), a current detector (5 ), a filter circuit (6), an auto-heterodyne inverter (7) producing a square voltage and provided with a synchronous signal output (8) and an adjustment circuit (9). The characteristic of the present invention is that a direct voltage (1) modifying within determined limits is applied via the sampler (2), the current detector (5) and the filter circuit (6) to an input of the auto-heterodyne inverter (7) whose synchronous signal output (8) is brought to the synchronization input (4) of the sampler (2). An output (13) of the current detector (5) providing a signal proportional to the average current is connected to an input (10) of the adjustment circuit (9), while a reference signal (14) determining the value current is supplied to the other input of the adjustment circuit (9). The output of the control circuit (9) is connected to the control input (3) of the sampler (2). The output of the inverter (7) simultaneously forms the alternating current output of the circuit.
