Working Principle Of Voltage Regulator How Does A Voltage Regulator Work?

Static Voltage Stabilizer is used to adjust the circuit and control the circuit, and to power the machine so that it can work normally. Let's take a look at the types and working principles of the voltage stabilizer.

First, the principle of the single-phase direct voltage regulator. The single-phase direct voltage regulator is constructed using the principle of the autotransformer. It should be noted that when the input voltage is higher than 220V, the transformer will automatically work in the step-down state, but if the input voltage is lower than 220V, the transformer will automatically work in the step-up state. The difference between this type of voltage regulator and the transformer is that the input point A can slide arbitrarily from 0V to 250V, so we can adjust the input point of the input voltage at any time to adjust the voltage to meet the constant voltage.

Secondly, the working principle of the three-phase voltage regulator. The working principle of the three-phase voltage regulator is to connect three relatively stable voltage units to use them, as long as the voltage is stable. The three sliding arms of the three-phase voltage regulator are all adjusted independently by a motor, so the voltage regulator is also a three-phase split-adjustment voltage regulator, that is, their working principle is exactly the same as that of the single-phase voltage regulator.

How does the voltage regulator ensure continuous output? Here we need to use the professional terminology of the voltage regulator to explain that the voltage regulator must change the number of turns of the contact coil by moving the carbon brush during the voltage regulation process. It should be noted that it is required to always keep in contact with the coil during the adjustment, otherwise the power will be cut off immediately.

In addition, the household AC voltage regulator is generally a simple type. It adds a control winding on the basis of a transformer, and then applies a direct current to this winding through these. After that, the iron core of the transformer will reach a semi-saturated state today. By adjusting the size of the DC control current, the iron core can be adjusted to enter a saturated state to adjust the output voltage.

In general, the working principle of the voltage regulator is actually the same as that of the sliding rheostat. The voltage at both ends of the electrical appliance is changed by adjusting the number of turns of the connected resistance wire.
