Which Transformer Is Used In A Servo Voltage Stabilizer – Transconind

A buck-boost transformer is used in a servo voltage stabiliser. This type of transformer works together with a servo motor to alter the voltage either UP or DOWN depending on the voltage variations of the input supply. Servo voltage stabilisers are useful for maintaining a steady voltage level to equipment which require such a precise input voltage where the main supply voltage changes frequently. Here’s a breakdown of its function:

Voltage Sensing: The input voltage is continuously checked by a control circuit. Servo Motor Control: Whenever there is change in the input voltage, the control system produces a signal to a servo motor associated to the variable winding of the transformer. Adjusting Voltage Output: The servo motor increases or decreases the position of a contact on the buck boost transformer winding. This causes the voltage to increase or decrease while at the same time ensuring that the output voltage remains constant.

Components

• Buck-Boost Transformer: The active device or element whose output voltage varies with the variations of the input voltage.
• Servo Motor: Electronically set up to allow for mechanical adjustment for fine tuning of voltages of the transformer.
• Control Circuit: Perceives variations in the input voltage, and then gives commands to the servo motor to make changes accordingly.
• Carbon Brush Assembly: Connected to another variable winding, thus enabling independent and continuous variation of voltage across it without interruption of current.

Uses Of Buck-Boost Transformers

The buck-boost transformers employed in servo voltage stabilisers are particularly important in safeguarding delicate operational electrical appliances as medical equipment, industrial processes, telecommunication networks, air conditioners, and refrigeration plants.

Advantages

Precise Voltage Regulation: It is characterised by high accuracy of output voltage stability.

Smooth Operation: The changes are made to the voltage of the electrical supply gradually when the servo motor is used, hence reducing the loads on other electrical equipment.

Durability: Buck-boost transformers are more reliable due to its ability to operate continuously for a long period on various industrial and business applications.

Thus, in servo voltage stabilisers, buck-boost transformers are of tremendous importance, controlling voltages and protecting delicate appliances against fluctuations.
