LANDANDRA POLINOMER GENERATOR

The invention relates to electrical engineering and can be used in power electronics to form sinusoidal functions with a set frequency.

There is a known oscillation generator (5M LepperaKOB, Γ.Μ.Γρο3ΑθΒ. SneKjpoHHbie cxeMbi Ha onepauwHHbix ycM / wTenax. Knee, TexHMica, 1983, οτρ. 88) containing a frequency generator, two integrators, inverting amplifier, functional converter.

The main drawback of the oscillator is limited functional capabilities.

The purpose of the invention is to expand the functional possibilities.

This is achieved by the following: - The Ljubljana polynomial generator contains a frequency generator, two integrators, an inverting amplifier and a functional converter.

The distinctive features of the technical solution are characterized by the activation of a functional pan / gate connected to the frequency generator at the output of the designated DC-block. The other two outputs of the assigned DC block are connected by a series of two integrators whose capacities are connected to the frequency generator switches and the linear function generator, whose capacity is connected to another generator switch. For the second integrator, the inverted amplifier, the linear function generator and the source of the correction voltage are switched on at the input of the summator.

The schematic diagram of the ligand polynomial generator is shown in FIG. 1, using the following designations: 1 - set of DC voltage; 2, 3 - integrators with their respective capacitors 4. 3; 6 - linear function generator with capacitor 7; 8 - frequency generator; 9, 10, 11 - frequency generator switches: 12 -functional converter; 13 - inverse amplifier; 14 - source of correction voltage; 15 - summer; 16 - load.

The proposed Ljubljana polynomial generator contains a set of DC voltage 1, with an output integrator 2 coupled to a capacitor 4, a linear function generator 5 with a capacitor 7, and a functional converter 12 connected to a frequency generator 8. An integrator 3 with capacitor 5 is switched on by a number of integrators 2, with output connected to inverse amplifier 13. Frequency generator switches 9, 10, 11 are connected in parallel to capacitors 4, 5, 7. Linear function generator 6, inverter amplifier output and correction voltage source 14 are connected to the input of the summator 15 at which output 16 is switched on. .

The Ljubljana polynomial generator works as follows.

The voltage value of the applied DC voltage 1 is applied to an integrator 2, the output voltage of which is re-integrated with the second integrator 3 to obtain a quadratic relationship voltage. Simultaneously, when running the linear function generator 3, form a triangular-shaped voltage that corresponds to the linear member of the Ljubljana polynomial. The capacitor 4, 5, 7 discharge time is determined by switches 9, 10, 11 of the frequency generator S. protrusion in line.

By summing the triangular tension of block 6, the inverse quadratic correlation voltage of the block 13 and the voltage of the correction source 14 provided by the summer 15 are obtained on a load 16 sinusoidal voltage coil. Thus, the capacitor charge 4. 5, 7 takes place at the positive pulse of the frequency generator, but its discharge - at the negative pulse of the frequency generator.

Advantage of the offered solution - it is possible to expand the functional possibilities. You can simultaneously change the amplitude to frequency for the sinusoidal voltage to be formulated over a wide frequency range, as well as ensure the accuracy of the transformations.
