One of the most powerful and reliable custom power supplies is the Dynamic Voltage Restaurator (DVR) (the power supply system). This is a collection of powered devices that mitigate the voltage drops and easily recover the pre-default load voltage. Its best advantage of the DVR is to keep users connected and maintain reliable performance stability and consistent quality voltage. A solar photovoltaic failure is given in this dissertation in conjunction with the unbalanced (linear, nonlinear) load voltage reduction in the ANN DVR control unit protecting the critical load
