Dynamic voltage restoration (DVR) is a method of overcoming voltage sags that occur in electrical power distribution.

The fundamental principle of dynamic voltage restoration is to insert a voltage of the magnitude and frequency essential to renovate the load side voltage to the preferred amplitude and waveform, yet when the source voltage is unstable or distorted. In general, devices for dynamic voltage restoration utilize gate turn off thyristors, (GTO) solid state power electronic switches in a pulse-width modulated (PWM) inverter construction. The DVR can produce or absorb separately convenient real and reactive power at the load side. In other words, the DVR is a solid state DC to AC switching power converter that injects a set of 3- phase AC output voltages in series and synchronicity with the distribution and transmission line voltages.

The basis of the injected voltage is the commutation process for reactive power exact and an energy source for the real power exact. The energy source may differ according to the design and producer of the DVR, but DC capacitors as well as batteries drawn from the line all the way through a rectifier are often used. The energy source is naturally connected to the DVR via its DC input terminal.

The phase angle and amplitude of the injected voltages are inconsistent, thereby allowing real and reactive power control exchange between the dynamic voltage restorer and the distribution system. As disclosed, the reactive power switch over between the DVR and the distribution system is generated within by the DVR with no AC passive reactive components.
