High Efficiency Automatic Voltage Controller with Battery

The automatic voltage regulator consists of an AC-AC converter, knife switch (QS), molded case circuit breaker (QF), contactor (KM), and compensation transformer. It utilizes controlled power electronics for bidirectional energy flow. During operation, it monitors grid voltage in real-time. If deviations occur, it controls the AC-AC converter to adjust the voltage, ensuring the load terminal voltage meets the set value. The knife switch facilitates bypass during maintenance, and the contactor manages load connection/disconnection in compensation mode. This system ensures stable voltage regulation.

high efficiency automatic voltage controller

Description

Automatic Voltage Controller

The Automatic Voltage Regulator (AVC) integrates an AC-AC converter, knife switch (QS), molded case circuit breaker (QF), contactor (KM), and compensation transformer. Utilizing fully controlled power electronics, the AC-AC converter enables bidirectional energy flow. The knife switch (QS) facilitates maintenance and bypass operations. The contactor (KM) manages load connection/disconnection during compensation.

Features

Real-time Grid Voltage Monitoring: The AVC continuously samples the grid voltage, ensuring it aligns with the set value.
Bidirectional Energy Flow: The AC-AC converter's controlled power electronics enable efficient bidirectional energy flow, enhancing overall system performance.
Bypass Capability: The knife switch (QS) provides a bypass option during maintenance, ensuring uninterrupted power supply.
Load Connection/Disconnection: The contactor (KM) efficiently handles the connection and disconnection of loads in compensation mode.
Voltage Regulation: In the event of grid voltage deviations, the AVC promptly controls the AC-AC converter to output voltage with the same or opposite polarity, regulating voltage in series.
Compensation Transformer Adjustment: The compensation transformer in the main circuit adjusts voltage amplitude and polarity to maintain the load terminal voltage at the set value.
Integration with Battery: The AVC integrates seamlessly with a high-efficiency automatic voltage controller featuring a battery. This enhances energy storage capabilities and ensures a stable power supply even during fluctuations or interruptions.
