Stabilisierte Speiseschaltung fuer ein Fernsehgeraet |
摘要 |
A rectified supply voltage from an AC utility outlet is chopped under the control of a recurrent pulse in the load circuit, specifically the flyback pulse of the horizontal sweep circuit of a television receiver, with the aid of a normally blocked chopping transistor connected to be unblocked by an intermittent biasing current from a secondary winding of a transformer whose primary winding acts as an inductance of a smoothing network for the chopped supply voltage. The resultant reduced output voltage is stabilized by the provision of a Zener diode in the input of either the chopping transistor or an ancillary transistor in series therewith. |
