Working principle

The DVR is connected in parallel in the system power grid. When the power grid voltage is normal, the power supply SCR turns on, and the power grid can directly supply power to the equipment. The bi-directional converter is in standby state, and the voltage fluctuation in the power grid is monitored in real time.
When the DVR detects the moment of abnormal voltage fluctuation, the equipment at the back end is converted to provide energy by super capacitors or other energy storage elements to ensure the normal operation of the electrical equipment is not affected.
When the power grid voltage returns to normal and the DVR judges that the power supply quality meets the requirements, the back-end device is converted to the power grid to continue the power supply, and the backup energy storage device is charged through the bi-directional converter.
