Abstract: Grid-connected PV inverter plays an important role in solar power applications. Since large-scale switching-off loads and grid faults may lead to voltage swell in the grid, the PV system should have high-voltage ride-through (HVRT) ability.

An grid-tied solar power inverter is the heart of a solar photovoltaic (PV) system, since it converts the free solar generated DC power into AC power in synchronisation with the utility grid.
Since large-scale switching-off loads and grid faults may lead to voltage swell in the grid, the PV system should have high-voltage ride-through (HVRT) ability. This paper found that there are three problems lying in single-stage PV system during HVRT due to its characteristics.
Voltage Ride-Through Voltage Ride-Through (VRT) refers to a solar inverter''s ability to remain connected and operational during short-term grid voltage disturbances, such as voltage sags, swells, or
Under grid voltage sags,over current protection and exploiting the maximum capacity of the inverterare the two main goals of grid-connected PV inverters. To facilitate low-voltage ride-through (LVRT),it is imperative to
