Circuit arrangement for generating a stabilized dc output voltage from an unstabilized d.c. input voltage as a rule, along with a link and a dc / dc converter which is fed from this

摘要

The output voltage corresponds to a specific nominal voltage. A series circuit comprises a series control element, an inductance and a timing circuit to which the d.c. voltage source outputs are connected. The inductance and the timing circuit are shunted by diodes with forward direction corresponding to inductive disconnection voltages. The output of the timing circuit delivers through a rectifier the stabilised d.c. voltage. a comparator controlled by the nominal voltage controls in turn the series control element. The timing circuit (T3) is in parallel with a series circuit consisting of a second diode (D2), whose forward direction corresponds to the inductive disconnection voltage of the inductance (L), and of a capacitor (C1) A circuit comprising a choke (L2) and possibly a resistor (R2) is in parallel with diode (D2).
