An Exploration And Analysis Of The Compensation Depth Coverage Of Dynamic Voltage Regulators

dynamic voltage stabilizer achieves system voltage regulation capability from 0% (voltage drops to zero) to 130% (voltage exceeds rated voltage) by high-speed detection of grid voltage fluctuations and configuring a backup energy storage unit between the DC bus and the inverter body. This structure allows the equipment to switch to compensation mode during severe undervoltage and overvoltage events, and restores the load-side voltage to a preset level by superimposing injected voltage.

In conjunction, dynamic voltage stabilizer for home activates the inverter to output positive voltage compensation from the energy storage module when the voltage is below the rated value, and adjusts the injection amplitude and phase through the inverter when the voltage is above the rated value, so that the load side maintains the rated voltage output.
