Description

"AND. From the outputs of the elements "And the pulses fall on the zero and single inputs of the triggers 6.

The analysis of the converter operation shows that the state of each of the triggers changes when the phase φ changes to Δf - -,

i.e., each of the flip-flops performs phase quantization φ with a step of -.

Thus, as the phase changes, the outputs of the flip-flops 6 have signals with a period of Df shifted relative to each other.

BUT

by -4

The movement direction selector 7 generates pulses at its outputs each time as soon as the phase changes by

. Depending

from the direction of movement, these pulses originate at one or another of the outputs of the movement direction selector.

The quantization step of the input value x is

In the case of using a phase sensor with an electrical reduction factor, the quantization step is equal to

The block diagram of the converter with improved accuracy is presented in FIG. 2

The input and output windings of the phase sensor 3 are connected to the inputs of frequency multipliers 9 and 10 with multiplication factors of 2 + 1 and, respectively. The outputs of the frequency multipliers are connected to the inputs of the mixer I. The output of the mixer is connected to the input of the zero-organ 4.

In this case, the quantization step is

In addition to the main purpose, the device can be used as an accurate speed sensor.
