Description
11 über den Eingangstransistor 12 versorgt werden. Sobald aber der Leistungstransistor 6 leitend geschaltet ist. wird die Betriebsspannung, die Ober die Diode 13 gleichgerichtet und über den Widerstand 14 und die Kapazität 15 geglättet ist, auch an den Emitter des Eingangstransistors 12 gelegt, und die Spar.nungseinspeisung erfolgt leistungsgeregelt über den Leistungstransistor 6, während der Eingangstransistor 12 in die Sperrphase übergeht und abschauet, sobald der geregelte Spannungswert erreicht wird. Diest hat den Vorteil, daß der Ein- gangstransistor 12 kleiner und für eine geringere Verlustleistung dimensioniert werden kann.11 are supplied via the input transistor 12. As soon but the power transistor 6 is switched on. the operating voltage is rectified via the diode 13 and via the resistor 14 and the capacitance 15 is smoothed, also to the emitter of the input transistor 12 placed, and the Spar.nungseinspeisung takes place power-controlled via the power transistor 6, while the input transistor 12 goes into the blocking phase and watches as soon as the regulated voltage value is reached. This has the advantage that the output transistor 12 can be dimensioned smaller and for a lower power loss.
Die erfindungsgemäße Schaltung eignet sich für alle im Eingang der Beschreibung erwähnten Betriebssysteme mit einem Spannungsbereich zwischen 6 und 120VoItThe circuit according to the invention is suitable for all operating systems mentioned at the beginning of the description with a voltage range between 6 and 120VoIt
