AVC-DVR is an innovative voltage stabilizing system designed to mitigate and eliminate the
effects of electrical disturbances such as severe voltage drops and spikes in critical industrial
processes.
2.How AVC-DVR works：
The main components of the AVC-DVR:
*Injection transformer
*IGBT voltage source inverter
*Fail-safe bypass
*DSP high-speed signal processor
*The AVC-DVR is connected in series between the grid and the protected load. It continuously monitors the input supply voltage, and as soon as it detects a deviation of the supply voltage from the rated level, the AVC-DVR quickly injects an appropriate compensating voltage through the IGBT inverter and the injection transformer.
*The AVC-DVR does not require an energy storage element, as it absorbs the additional energy required from the grid to compensate for the missing voltage.
