AVC-DVR
DYNAMIC VOLTAGE RESTORER
1-30KVA Single-phase 10-1600KVA three-phase

1.What is Automatic Voltage Compensator Dynamic Voltage Restorer (AVC-DVR)?

AVC-DVR is an innovative voltage stabilization system consisting of an inverter, compensation transformer and bypass. The compensating energy is taken from the grid by the converter, and the voltage drop compensation is 40% of the total correction, which can effectively control voltage drops and spikes, avoiding the economic and production losses caused by voltage fluctuations to the users.

3.How does it work?

AVC-DVR detects the grid voltage in real time based on the synergistic work of step-up/step-down transformer and inverter. When the grid voltage deviates from the nominal voltage value, the inverter is immediately controlled to inject the correction voltage into the main circuit through the series-connected compensation transformer to quickly and accurately compensate the load voltage to the nominal voltage value to ensure the loads to operate normally without being affected by the voltage abnormality.
