Principle Analysis of Single-phase AC Regulator

Principle Analysis of Single-phase SVC Direct Voltage Regulator

Point A is the input side of the single-phase regulator, and point B is the output side of the single-phase regulator

In fact, this type of voltage regulator with direct voltage regulator is made of the principle of autotransformer. In the figure, the AN side is the input side of the autotransformer, and the BN side is the output side of the autotransformer. If the input voltage is higher than the output set point 220V, the autotransformer will work in the step-down state. If the input voltage is lower than 220V, the autotransformer will work in the step-up state (shown in the figure is in the step-down state)

This regulator is different from the autotransformer mainly in that the input point A can slide arbitrarily between 0V and 250V. In this way, the input point of the input voltage can be adjusted at any time to meet the constant output voltage. Generally, we call point A on the input side as a sliding arm, which is driven by a motor through a deceleration device, and the steering of the motor is controlled by a voltage stabilizing control circuit.

The sampling circuit of the regulator monitors the voltage between the output two points of the regulator at all times. When the output voltage rises, the motor is controlled to move in the direction of the autotransformer step-down (as shown in Figure 2) when the output voltage reaches the desired voltage, stop Control motor movement. On the other hand, the control circuit controls the motor to rotate in the direction of the autotransformer boost. (Figure 3) Stop when the desired voltage is reached.

The capacity of this type of voltage regulator is fully borne by the autotransformer of the output voltage transformer, but due to the influence of its manufacturing process, it cannot be made large and can only be adapted to low-power occasions. To phase the power of the regulator to do more, it is necessary to add a compensation transformer to achieve the power of the regulator to expand.

three phase regulator working principle:

The three-phase voltage regulator is actually to connect the three voltage regulator units together with a "Y" connection. Then the control circuit board and motor drive system are used to control the voltage regulating transformer to achieve the function of stabilizing the output voltage. If the sliding arms of the three voltage regulating transformers are all driven by a motor, the voltage regulating method is a unified regulator. If the sliding arms of the three voltage regulating transformers are independently adjusted by three motors, the voltage regulator is a three-phase split regulator. Their working principle is exactly the same as that of a single-phase regulator.

Three phase voltage is too low with the regulator useful?

Three phase voltage is too low with the regulator useful?

Voltage instability can be solved with a voltage regulator, the answer is yes, the voltage regulator can solve the problem of low voltage. However, when purchasing a voltage regulator, it is necessary to test the voltage fluctuation value of the region. When purchasing a voltage regulator, the voltage regulation range of the voltage regulator must be greater than the voltage fluctuation value of the region.

How does the regulator work?

Voltage regulator is used to adjust the circuit and control circuit, power supply for the machine to make it work normally, then we will look at the type and working principle of the voltage regulator. First of all, the principle of single-phase direct voltage regulator. Single-phase direct voltage regulator is composed of the principle of autotransformer. It should be noted that when the input voltage is set, if the output point is higher than 220V, the transformer will automatically work in the step-down state. However, if the input voltage is lower than 220V, the transformer will automatically work in the step-up state. This regulator is different from the transformer mainly in 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 meet the constant voltage.

How to know the price of the regulator

We in the process of electricity, more or less will encounter voltage instability, instantaneous fluctuations, voltage regulator is to solve such problems. Many people are concerned about the price of regulators when purchasing regulators. However, there are many brands of regulators on the market, and the quality of regulators is also uneven, so the price is also very different.
