II. Main Types of Voltage Stabilizers​

1. Servo – Controlled Voltage Stabilizers​

Servo – controlled voltage stabilizers are one of the most common types. They work by using a servo motor to adjust the position of a tap on a transformer. When the input voltage changes, a voltage sampling circuit detects the change and sends a signal to the control circuit. The control circuit then drives the servo motor to move the tap, adjusting the output voltage.​

1.1 Working Principle Details​

The servo motor is a key component in this type of stabilizer. It rotates precisely according to the control signal, ensuring accurate voltage adjustment. The transformer, with multiple taps, provides different voltage ratios. By changing the tap position, the output voltage can be increased or decreased to maintain stability.​

1.2 Performance Characteristics​

Servo – controlled voltage stabilizers offer relatively good voltage regulation accuracy, usually within ±1% – ±3%. They can handle a wide range of input voltage fluctuations and are suitable for many general – purpose applications, such as powering office equipment, home appliances, and small – to – medium – sized industrial machinery.​

2. Contact – Type Voltage Stabilizers​

Contact – type voltage stabilizers use mechanical contacts to switch between different voltage – regulating taps. When the input voltage deviates from the set value, the control system triggers the contactor to change the connection of the transformer taps, thereby adjusting the output voltage.​

2.1 Working Principle Details​

The contactors in these stabilizers are electromagnetic devices. When the control signal is received, the electromagnetic coil in the contactor is energized, attracting the moving contact to connect with the appropriate tap on the transformer. This mechanical switching action changes the voltage transformation ratio.​

2.2 Performance Characteristics​

They are relatively simple in structure and have a lower cost compared to some other types. However, the mechanical contacts are prone to wear and tear over time, which may lead to contact resistance problems, reduced reliability, and the need for frequent maintenance. The voltage regulation accuracy is generally around ±5%, which is less precise than servo – controlled stabilizers.​

3. Contactless Voltage Stabilizers (Taking BKPOWER’s BK – AVR as an Example)​

Contactless voltage stabilizers, such as BKPOWER’s BK – AVR, utilize advanced semiconductor technology for voltage regulation. Instead of mechanical contacts, they use electronic components like thyristors or IGBTs (Insulated Gate Bipolar Transistors) to control the voltage.​

3.1 Working Principle Details​

The BK – AVR stabilisateur de tension sans contact from BKPOWER works by precisely controlling the conduction angle of thyristors or IGBTs. When the input voltage changes, the control circuit quickly detects the change and adjusts the conduction angle of the semiconductor devices. This adjustment changes the output voltage, ensuring a stable power supply. The use of semiconductor technology enables fast response times, typically within milliseconds, which is much faster than mechanical – based stabilizers.​

3.2 Performance Characteristics​

BK – AVR contactless voltage stabilizers offer high – precision voltage regulation, usually within ±0.5%.
