Invention of a contactless voltage relay with an adjustable reset ratio

The purpose of this article is to apply the relay effect observed in semiconductor circuits to create a contactless relay voltage with an adjustable return coefficient, connected in one device sensitivity to the input voltage and switching of powerful loads to high currents. A dynamic circuit is investigated, consisting of an adjustable semiconductor, in series with a parallel circuit of a capacitor and a resistor, which is one of the parts of the proposed relay device with a sinusoidal frequency of voltage fluctuations on the load. To study the operating modes and analyze the device circuits, it is recommended to use numerical methods using computer technology.The principle of operation and experimental characteristics of the developed device are presented.
