What are the different types of voltage regulators

Before heading to the store to buy a voltage regulator and then do not regret the purchase, you need to understand some of the stabilizer performance you need type. In this article I will tell you about the existing species, and voiced their pros and cons.

Relay

We'll start with you analysis of existing species with the most common devices. The principle of operation of this product lies in the following: on the winding of toroidal transformers are switched by power relays.

Interior organization: toroidal transformer, control board and relyushki gear change.

This type stabilizers is extremely sensitive to overload (up to 90% of failures connected with front-loaded), as such a product very poorly transfers motor inrush currents.

Pros: reasonable price, small dimensions.

Minuses: Voltage adjustment is staggering. Can not be used in conjunction with a powerful electric equipment. Noisy relay. In a quiet environment switching sound may well get on your nerves. Low voltage regulation accuracy.

Despite the presence of a large number of disadvantages, this type of stabilizer is popular.

Now let's move from mechanics to electronics.

electronic

This type stabilizers may be configured as triac or thyristor. Here, too, use a transformer with the management board, only switching between the windings by means of triacs.

Due to this such a product has a high efficiency, and the response speed is quite high. As such stabilizers are not as sensitive to accelerations, and starting currents of motors and pumps are quite capable of this stabilizer. Still they can easily tolerate a negative temperature, which allows them to be installed in unheated storage.

pros: Quiet operation, commutation step rate is 20 ms, smooth adjustment. Higher reliability due to the absence of moving mechanical parts constantly.

Minuses: Pretty high cost. Interference, making it difficult to work the radio, and also do not allow the fine to use a musical instrument.

Next on our list is the product, to combine all the best of the above two types of stabilizers.

Electromechanical

These voltage regulators may also be referred servomotornymi or servocontrol. Moreover, this type can be called a middle ground between the relay and electronic CH (voltage regulators).

This product reversible actuator moves the brush along the windings of the transformer, due to this continuous adjustment is achieved without any steps. It is a very popular model, which has the following advantages:

pros: Adjust according to the principle of a rheostat, high precision control, no distortion sine wave, can withstand short-term overload.

Minuses: Low control speed due to the use of electric drive. Reliability is not so high because of the presence of moving parts. The graphite brushes require inspection and periodic replacements. It can not be used at low temperatures. In networks with sharp jumps apply undesirable.

Now let's look already to some extent outdated stabilizers.

ferroresonance

This type stabilizers implemented on ferroresonance circuit voltage effect in the capacitor-transformer.

The advantages include: speed, very high service life, high reliability, precision stabilized output voltage.

Minuses: Very high noise regulation is possible only within a narrow range, idling is not possible, a considerable weight.

We can say that these stabilizers in the past, but they can still be found. And now let's look at the most modern and increasingly gaining popularity inverter stabilizers.

inverter stabilizers

This type of stabilizer operates as follows: at the entrance of the alternating current passing through the filter subsequently converted to DC, and then outputs the AC inverter again with ideal parameters.

pros: High range of voltage regulation, the minimum error of the output, compact size and low weight, the ability to filter high frequency noise, keeps working to -40 degrees

Minuses: The high price is not designed for heavy loads.

These are all the main types of stabilizers submitted so far. Knowing the strengths and weaknesses of each type, you can choose the one that will suit your requirements and at affordable prices.
