An analog-to-digital converter is the future of electric drive control circuits

On the possibilities of analog-to-digital converterswas said for a long time. Even before the moment of their invention, discussion of their possibilities did not reach unless to science fiction novels. Their appearance promised huge prospects in electronics, right up to the invention of artificial intelligence. Indeed, the analog signal is "not clear" to such a device, such as a processor. At the same time as the digitized analog signal is "understandable" to all devices. The connecting link in this case is an analog-to-digital converter. This is a universal device that allows you to convert an analog signal into a discrete code.

The need for such devices wasis dictated by the time itself. With the development of electronic circuits, the first digital devices appeared. They possessed good controllability, high accuracy and good performance characteristics. They could perform many tasks that could not be solved with a conventional analog circuit. As an example, you can compare the first computer with electronic tubes, which was the size of a two-story house, and a modern laptop model.

But nevertheless, from the analog signalthe developers of electronic circuits have not refused to this day. The fact is that most of the existing sensors work with it. In addition, it continues to be used in designing and perfectly copes with the functions assigned to it. It is more "informative" than its digital counterpart, and the devices on its

based have excellent speed. This is important in the operation of control circuits, for example, an electric drive.

An analog-to-digital converter is designed to enable the two devices to work together.

With it, you can convert, for example, a signal from an analog temperature or speed sensor to binary code and use the microcontroller to control the state of the control object.

In addition to protection and control schemes, analog-digitalThe converter is successfully used in the management of electric drives of various capacities. The only limitation in this case is the speed of the data collected on its basis

device.Well-known companies produce self-adjusting control units, which are used to ensure reliable operation of engines. For example, the frequency converter includes an analog-to-digital converter that is able to "transform" the signals from the sensors and return the information to the processor.

A simpler example of their use may beserve as an ordinary voltmeter, which includes a digital converter. In many cases, such devices work much more efficiently than their analogous counterparts.

Instruments such as analog-digitalconverters, are firmly embedded in existing electronic circuits. The development of the technology of their manufacture and the appearance of new principles of signal transformation are on the way of increasing the speed of these devices.
