Active Voltage Conditioner
An Active Voltage Conditioner (AVC) is a high-speed power electronic device designed to protect sensitive industrial equipment—like industrial sites servers or specialized LiDAR processing units from voltage sags and voltage swells. In environments where the local grid can be unstable due to infrastructure rebuilding or heavy industrial loads, an AVC acts as an active filter that stabilizes power in real time. The Mechanism Unlike a standard UPS (Uninterruptible Power Supply) which relies on batteries to take over when power fails, an AVC is an injection system.
Continuous Monitoring: The AVC constantly monitors the incoming supply voltage from the grid.
Detection: If the voltage drops a sag or spikes a swell, the AVC detects the deviation within milliseconds typically less than 2ms.
Correction (Injection): The device uses an internal inverter to inject the missing voltage into the line in real-time. If the grid drops to 80%, the AVC adds the missing 20% instantly.
Phase Alignment: It ensures the injected voltage is perfectly in phase with the grid, so the downstream equipment never "feels" the disturbance.
