Description

one

The invention relates to electronics and can be used in devices: computers and automation.

Constant-to-frequency converters are known that contain an input winding located on the magnetic core, and elements that convert the induction of the magnetic field of the core into a cluster. The disadvantages of the known converters are the complexity and bulkiness of the circuit because controlled sensors, magnet excitation of frequency sensors and magnetic screens,

The purpose of the invention is to simplify the design.

To do this, in the magnetic field of the core there is a solid-state functional element with cord /) current, made in the form of a distributed structure and having kentricheski located, electrodes, connected in series to the circuit of the reference current source, and

us elements shooting | output j signal.

The drawing is a schematic diagram of the DC / DC converter to frequency.

The converter contains magnetic core 1 with winding 2, forming the converter input, solid-state functional element 3, located perpendicular to the magnetic flux and consisting OF concentrically arranged electrodes. The external electrode consists of vectors 4 5, to which resistors 6, 7 are connected, and 1 internal electrode 8 is made in the form of a solid circle connected to the case. Resistors 6, 7, from which they remove output signals, are connected to resistor 9, To which the voltage source 10 is connected. The resistor 9 and the source 1O form a reference current source. Distributed diode structures of compensated semiconductors based on silicon, germanium, halide arsenide, four-pole p-th-p-n structures, structures with semiconductor phase transitions (M & with g wrapping

Analog signal coming in on

Motau 2 converter, C creates a magyit | yov field proportional to the ttocTyif value of the transmitted signal and directed perpendicular to the plane of the solid-state functional element ZG

After switching on the voltage source

10 each electrode of a solid-state fuzzing element 3 goes into a region of negative differential resistance. Under the action of an external transverse magnetic field, the current cord 11 makes a peridic motion; at a speed proportional to the magnitude of the magnetic field. The moving current cord 11 resists a voltage pulse on the resistors 6, 7, which follow the "dst, the dianal magnitude" of the analog signal; and put in phase by 180 one relation

respectfully of the other. An increase in the number of sectors of the external electrode to | i) makes it possible, from the C outputs, to receive signals proportional to the magnitude of the analog signal and shifted (| by 2) G | s degrees one relative to another.
