Abstract
Description
In der herkömmlichen Schaltungstechnik wird für eine Gleichspannungsversor gung aus Platz- und Kostengründen häufig ein komplexer Vorwiderstand (Hoch spannungskondensator) verwendet, der Speicherkapazitäten auf die benötigte Niederspannung auflädt. Die Spannung der Speicherkapazitäten wird bei einer stabilisierten Gleichspannungsversorgung begrenzt, da sonst die Niederspannung auf Potential der Versorgungsspannung hoch läuft. Der Stand der Technik ist für die Erzeugung einer positiven Spannung aus den Zeichnungen 1 und 2, für die Erzeugung einer positiven und einer negativen Spannung aus den Zeichnungen 3 und 4 ersichtlich.In conventional circuit technology, a DC voltage supply is used a complex series resistor (high voltage capacitor) used, the storage capacities to the required Low voltage charges. The tension of the storage capacities at one stabilized DC voltage supply limited, otherwise the low voltage runs up to the potential of the supply voltage. The state of the art is for the generation of a positive voltage from the drawings 1 and 2, for which Generation of positive and negative voltage from drawings 3 and 4 can be seen.

Diese Begrenzung wird i. d. R. durch Zenerdioden realisiert, welche den von der nachgeordneten Schaltung nicht benötigten Strom ableiten. Dabei entsteht insbe sondere bei größeren Niederspannungen (größer als ca. 10 Volt) und bei nachge ordneten Schaltungen mit größeren Lastwechseln erhebliche Wirkleistung in der Zenerdiode. Das ist ein erheblicher Nachteil von Schaltungen gemäß dem Stand der Technik, denn damit wird der Wirkungsgrad der Spannungsversorgung ge senkt und die entstehende Wärme hat in den meisten Anwendungen negativen Einfluß auf die umgebende Schaltung. This limitation is i. d. R. realized by Zener diodes, which the of the downstream circuit derive unnecessary current. This creates in particular especially with larger low voltages (greater than approx. 10 volts) and with secondary arranged circuits with larger load changes considerable active power in the Zener diode. This is a significant disadvantage of prior art circuits the technology, because it will increase the efficiency of the power supply lowers and the heat generated has negative effects in most applications Influence on the surrounding circuit.

Die Schaltungsanordung dient dazu, die Wirkleistung herkömmlicher, stabilisierter Gleichspannungsversorgungen zu reduzieren. Erreicht wird dies dadurch, daß der Ableitstrom, der über die Zenerdiode aus der Speicherkapazität abgeleitet wird, z. B. über einen Widerstand gemessen wird und bei Überschreiten einer wohldefi nierten Schwelle der Vorschaltkondensator mittels eines Triacs oder Thyristors gegen Masse kurzgeschlossen wird. Ein kurzgeschlossener Kondensator erzeugt bekanntlich nur Blindleistung (bis auf minimale Dielektrizitätsverluste) und somit keine Wärme.The circuit arrangement serves to stabilize the active power in a conventional manner Reduce DC power supplies. This is achieved in that the Leakage current, which is derived from the storage capacity via the Zener diode, e.g. B. is measured via a resistance and if a well-defined is exceeded nated threshold of the ballast capacitor using a triac or thyristor is short-circuited to ground. A shorted capacitor creates as is well known, only reactive power (apart from minimal dielectric losses) and thus no warmth.
