Dynamic Voltage Restorer based on a New Step-up Switched Capacitor Multilevel Inverter for Fault Ride-Through of Wind Generators

Providing capability to keep wind and renewable sources connecting to the grid by Dynamic voltage restores (DVRs) during transient low-voltage and over-voltage conditions is a recommended solution. But, increasing the grid nominal voltage, the power switch stresses increase significantly. Also, the generated voltage by DVRs may contain high total harmonic components. In this regard, this research ...
