Dynamic Voltage Regulator (AVC) is a device that manages voltage quality problems such as voltage fluctuations in the three-phase power grid and low power factor in the distribution network.
The whole machine of the dynamic voltage regulator (AVC) is connected in series to the outlet of the distribution transformer through the coupling transformer system side, with full automatic control, real-time detection of grid voltage data, and comparison with the set output voltage. The voltage to be compensated is flexibly controlled through the converter part, with bidirectional adjustment, flexible setting of output voltage, and a large adjustment range. The inverter output voltage is coupled to the system side through the coupling transformer, and after superimposed with the system voltage, the purpose of compensating the voltage is achieved; that is, only the difference part needs to be compensated to achieve the minimum compensation power.

| How it works | AVC is composed of rectifier, inverter, compensating isolation transformer and bypass. When the grid voltage deviates from the set value, the dynamic voltage regulator (AVC) supplies power to the load in different ways according to the depth of grid drop. It controls the output of the power module on the PWM inverter side and then adds appropriate compensation voltage to the main circuit through the series coupling transformer to quickly adjust the load voltage to the rated value. The voltage sag compensation depth of 40% is completely corrected, thereby eliminating the impact of the voltage sag from the grid input end on the load. | ||||||
