4.2. Power Circuit Design of DVR Components
The power circuit of the proposed Dynamic Voltage Restorer (DVR)
topology in a three phase system is shown in Figure 4.4. It connected between
three phase sources and nonlinear load. As seen from the Figure 4.2, there are three
main elements, which are considered in the design of a DVR.
