Introduction
Voltage fluctuations can severely impact the performance and lifespan of electrical equipment. A servo controlled voltage stabilizer is designed to provide a stable output voltage by correcting any fluctuations in the input voltage. This ensures the optimal operation of electrical devices, safeguarding them from potential damage. In this article, we will explore the working principle of servo controlled voltage stabilizers, their components, and their benefits.
What is a Servo Controlled Voltage Stabilizer?
A servo controlled voltage stabilizer is an electromechanical device that maintains a constant output voltage level irrespective of variations in the input voltage. It achieves this through the use of a servo motor, which adjusts the position of the variable transformer to regulate the voltage.
Components of a Servo Controlled Voltage Stabilizer
- Servo Motor: A critical component that drives the movement of the variable transformer to adjust the voltage.
- Variable Transformer (Auto Transformer): Modulates the voltage by altering its winding ratios based on the servo motor's movement.
- Control Circuit: Monitors the input voltage and commands the servo motor to make necessary adjustments.
- Buck-Boost Transformer: Ensures the output voltage is stepped up or stepped down as required.
- Relays: Switches that facilitate the control of voltage levels within the stabilizer.
- Carbon Brushes: Conduct electricity between stationary wires and moving parts of the transformer.
Working Principle of Servo Controlled Voltage Stabilizer
1. Detection of Input Voltage
The stabilizer’s control circuit continuously monitors the incoming voltage. When it detects a deviation from the predetermined voltage level, it sends a signal to the servo motor.
2. Signal Processing
The control circuit processes the deviation signal and determines the required adjustment. It then instructs the servo motor to either increase or decrease the voltage.
3. Adjustment by Servo Motor
The servo motor, responding to the control circuit’s command, moves the shaft connected to the variable transformer. This action changes the transformer's winding ratio, thereby adjusting the output voltage.
4. Voltage Regulation
The variable transformer modulates the voltage, which is then fine-tuned by the buck-boost transformer to ensure it matches the desired output. The stabilizer steps up or steps down the voltage as necessary.
5. Continuous Monitoring
The system continually monitors the output voltage to ensure it remains within the acceptable range. The control circuit and servo motor work together to make real-time adjustments, maintaining a stable output.
