Abstract
Abstract A pulse generator circuit includes a unijunction transistor having an emitter electrode connected to a common point in the connection between the resistor and capacitor of an RC circuit, a base 1 electrode, a base 2 electrode and an interbase path. A Hall generator is connected in series with the unijunction transistor via the interbase path of the transistor and has one control current electrode connected to the base 1 electrode of the unijunction transistor, another control current electrode connected to the capacitor of the RC circuit, one Hall voltage electrode connected to the negative polarity terminal of a source of DC voltage and another Hall voltage electrode galvanically connected to the control circuit of an electronic switching component.
