Description
Im einfachsten Fall kann ein elektrischer Stromstoß dadurch erzeugt werden, daß eine Spannungsquelle direkt kurzzeitig an den Verbraucher gelegt wird. Eignet sich aber die vorhandene Spannungsgröße nicht, so muß@ durch ein Umformungsglied die' Spannung verändert werden. Es ist bekannt, daß Belastungsänderungen in Wechselstromkreisen zu Phasenverschiebungen führen, was besonders bei der Verwendung von schwingenden Stromrichtern eine Zerstörung hervorrufen kann.In the simplest case, this can generate an electrical surge that a voltage source is applied directly to the consumer for a short time. However, if the existing stress size is unsuitable, @ must be caused by a deformation element the 'tension can be changed. It is known that changes in load in AC circuits lead to phase shifts, which is especially true when using oscillating Converters can cause destruction.
Es ist nun gefunden worden, daß durch einen entsprechend großen Kondensator, welcher über einen an sich bekannten Zerhacker mit- Aufwärts-Transformator und nachfolgendem Gleichrichter langsam aufgeladen wird, die Stoßbelastung gedeckt werden kann, während der Strom über das Umformungsglied klein gehalten werden kann.It has now been found that by means of a correspondingly large capacitor, which via a known chopper with step-up transformer and the following Rectifier is charged slowly, the shock load can be covered while the current through the conversion element can be kept small.
Die Abbildung zeigt diese Schaltweise. Die vorhandene Gleichspannung U1 liegt am schwingenden Wechselrichter Z. Über den Transformator T wird die Spannung auf den erforderlichen Wert gebracht. Die gleichgerichtete Sekundärspannung lädt über den Widerstand R den Kondensator C2 auf. Die aufgespeicherte elektrische Energie im Kondensator C2 ist so bemessen, daß die Stoßbelastung gedeckt wird. An Stelle des Widerstandes R kann eine Drossel geschaltet werden.The illustration shows this switching method. The existing DC voltage U1 is connected to the oscillating inverter Z. Via the transformer T, the voltage brought to the required value. The rectified secondary voltage charges across the resistor R to the capacitor C2. The stored electrical energy in capacitor C2 is dimensioned so that the shock load is covered. Instead of of the resistor R a throttle can be connected.
Die gefundene Schaltweise zur Erzeugung kurzzeitiger Stromstöße in Verbindung mit einem schwingenden Stromrichter ist vielseitig anwendbar.The switching method found for generating short-term current surges in Connection with a vibrating converter is versatile.
Sie kann z. B. Verwendung finden erstens zur Speisung von Magneten, zweitens, zur Erzeugung von Blitzlicht, drittens zur Erzeugung von: physiologischen Wirkungen bei Mensch und Tier, viertens zum Fang von Wassertieren durch das Einleiten der Entladungsstöße ins Wasser. Auf elektrisch zu .zündende Minen soll sich die Erfindung nicht erstrecken.You can z. B. are used firstly to supply magnets, second, to generate flashlight; third, to generate: physiological Effects on humans and animals, fourthly for catching aquatic animals by discharging the bursts of discharge into the water. The Invention does not extend.
Für den Fall, daß die Eingangsspannung Ui nur kurzzeitig wirksam ist, ist es zweckmäßig, einen entsprechend großen Kondensator Cl in den Eingang des Gerätes zu legen, wodurch die Belastungsspitze für die Stromquelle U1 sowie für das Gerät geringer wird.In the event that the input voltage Ui is only effective for a short time, it is advisable to insert a correspondingly large capacitor C1 into the input of the device to put, whereby the load peak for the power source U1 as well as for the device becomes less.
