Description

and improving the shape of the binary signal.

The supply chain is achieved by the fact that the device is autonomously equipped with an inverter, which contains the patterns and patterns of imprints and distribution panels, which is additionally equipped with a portable counter and a decoder, and the generator is equipped with a durable counter and a decoder, and the generator is equipped with a durable counter and a decoder; : x)} pulses through sequentially connected binary counter into the decoder is connected to the second input to distribute the bodies of pulses.

FIG. t shows a block diagram of the device in FIG. 2 - impuls-: On the output signal diagram.

The device for controlling an autonomous inverter contains a square pulse generator 1, a double counter 2, a decoder 3, a pulse distributor 4. From one generator output 1, the pulses go to binary counter 2, which is assembled according to a binary counter circuit with a number of code combinations at the output, equal to the duration of the counting cycle.

The code points from the output of counter 2 are received in parallel code to decoder 3. Decoder 3, depending on the output signal algorithm embedded in decoder-3, outputs the control signal to one of the inputs of the distributor UMiiyHb. Owl 4. This pulse gives permission for passing through the pulse distributor 4 a signal arriving at its second input from generator 1. When the generator pulse frequency 1 is inputted to generator 1 at the output of pulse distributor 4, the frequency of the single signal will change,

When the pulse duty cycle is turned off, the integral power of the video signal changes. The output signal can be a cyclic signal of any shape; sinusoid, sinus square / trapezoidal, and others with any number of phases, but no more than quantity, "; solid combinations at the output of binary counter 2 in one cycle .;

The cycle time depends on the sampling step of the output signal. The sampling rate depends on the required reproduction of the output signal.

So, for example, in order to get a sine wave at the output of the device, the sampling step of the electric distribution of electrical degrees (Fig. 2 shows 1/4 of the sinusoidal period 5 of the ONE phase), it is necessary for more accurate reproduction of the clock frequency of the generator I to be taken so the power of the sinusoid from O to 30 electrical degrees corresponding to

 The shaft had three clock frequency impulses, the power of the section from 30 to 60 electrical degrees corresponded to eight and “I”, and the power of the section from 60 to 90 electrical degrees corresponded to eleven pulses. The half-cycle will correspond to 66 times, 1M positions, each of which corresponds to one of the code combinations at the output of binary counter 2.

The decoder 3 must output a permitting signal when the code combinations corresponding to 4 to 6, 13 to 2O, arrive at the input,

5 22 to 33 positions (for 1/4 period); further in the same way. In order to reduce the cycle, which reduces the equipment of the degirator 3 and counter 2, the cycle can be limited to half-periods, and

A Q code combination corresponding to 180 (0) electrical degrees can be used to switch the polarity of the signal. With a maximum sampling step of 180 electrical degrees

5 decoder and pulse distributor

can be combined.

 The present invention may be

applied in any electrical

devices where you need to create

variable signals by converting direct current to alternating current. Since the sampling step can be (determined by the speed of the input switching elements), then

5, the output signal can be in a form sufficiently close to the ideal without the use of complex systems of generators and linear amplifiers. The device can be almost completely assembled on integrated circuits of any integration, which ensures high adaptability to the reliability of the device.
