Description

Die Erfindung bezieht sich auf einen Gleichspannungswandler nach dem Prinzip der vormagnetisierten Drossel mit zwei Eisenkernen, der bei gleichzeitiger Verwendung von hochpermeablem Material mit scharfem Sättigungsknick zum Kernaufbau, Parallelschaltung der Sekundärwicklungen beider Kernsysteme und Gleichrichtung des sekundären Wechselstromes echte Wandlereigenschaften erhält, wobei er keine magnetische Rückwirkung vom Sekundär- auf den Primärkreis erfährt, und über einen ohmschen Vorwiderstand an das Gleichstromnetz angeschlossen ist. The invention relates to a DC voltage converter according to the principle of the premagnetized choke with two iron cores, which with simultaneous Use of highly permeable material with a sharp saturation kink to build up the core, Parallel connection of the secondary windings of both core systems and rectification of the secondary alternating current receives real converter properties, whereby it is not magnetic Experience feedback from the secondary to the primary circuit, and via an ohmic series resistor is connected to the direct current network.

Da ein solcher Gleichspannungswandler keine Gegen-EMK auf induktivem Wege aufbringen kann, wird diese durch einen ohmschen Spannungsabfall erzeugt. Der der Primärspannung proportionale Strom dient dann der Steuerung des Sekundärstromes, wobei die Wandlerleistung dem Wechselstromnetz entnommen wird. Since such a DC / DC converter does not have back EMF on inductive Can raise paths, this is generated by an ohmic voltage drop. Of the The current proportional to the primary voltage is used to control the secondary current, whereby the converter power is taken from the AC network.

Erfindungsgemäß wird diesbezüglich nun der Vorschlag gemacht, den Vorwiderstand in die Primärwicklung einzubeziehen, indem diese Wicklung ganz oder teilweise aus Widerstandsmaterial ausgeführt ist. Lediglich zum Feinabgleich ist gegebenenfalls noch ein kleiner Vorwiderstand zweckmäßig. Abgesehen davon, daß man auf diese Weise den bisherigen hohen ohmschen Vorwiderstand einspart, ist hierdurch die Möglichkeit gegeben, ähnlich wie bei Wechselspannungswandlern in einer hochspannungstechnisch einwandfrei ausgeführten Lagenwicklung das Potential vom Höchstwert bis auf Null abzubauen. Bei Wechselspannungswandlern hat aber mit Rücksicht darauf, daß der Magnetisierungsstrom durch die Induktivität des Wandlers begrenzt wird, ein etwaiger Vorwiderstand nur insofern Sinn, als dieser gegebenenfalls zur Strombegrenzung dient. Die Einbeziehung des Vorwiderstandes in die Primärwicklung wäre aber sinnlos. According to the invention, the proposal is now made in this regard, the Include series resistance in the primary winding by removing this winding entirely or is partially made of resistance material. Only for fine adjustment is a small series resistor may be useful. Apart from the fact that one This saves the previous high ohmic series resistance given the possibility, similar to AC voltage converters in a high voltage technology correctly executed layer winding the potential from the maximum value to zero to dismantle. With AC voltage converters, however, it has to be taken into account that the magnetizing current is limited by the inductance of the converter, a possible series resistor only In so far as this serves to limit the current if necessary. Integration the series resistance in the primary winding would be pointless.

Die Erfindung ist in der Zeichnung beispielsweise dargestellt. P bezeichnet hierin die Primär-und S die am Wechselspannungsnetz liegende Sekundärwicklung des Wandlers. Die Messung erfolgt über einen Gleichrichter sowie über Glättungselemente durch das Meßinstrument J. The invention is shown in the drawing, for example. P. denotes the primary winding and S the secondary winding connected to the AC voltage network of the converter. The measurement takes place via a rectifier and smoothing elements by the measuring instrument J.
