dynamic voltage restorer (DVR)

A Dynamic Voltage

Restorer (DVR) is a dynamic voltage source that compensates for load changes, voltage drops, voltage spikes and other supply voltage disturbances. Dynamic Voltage Restorers are connected as supply components in the low-voltage network and compensate for short-term voltage fluctuations

. Thesupply voltage delivered by the Dynamic Voltage Restorer is constant and prevents malfunction of the equipment connected to the low voltage network due to unstable supply voltages.

DVR devices are often used in production facilities, they are connected to three-phase power and prevent the undesirable slowdown of the production process that can be caused by abrupt changes in the electrical power demand. The control is mainly based on power semiconductors such as IGBT and IGCT.
