DC fault ride through of multilevel converters [PDF]
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016 Modular Multilevel Converters (MMC) can provide significant advantages for power transmission applications, however there are remaining challenges trading off DC fault response, losses and controllability. Alternative multilevel converter topologies using combinations of full bridge and half bridge submodules or series switches allow for competitive ...

Photovoltaic inverters with fault ride-through Capability [PDF]
2009 IEEE International Symposium on Industrial Electronics, 2009 This paper presents a new control strategy that allow the photovoltaic system operate under grid faults without overpass the rated current and assuring sinusoidal currents. In the classic control strategies used in photovoltaic systems the power delivered to the grid remains constant when a fault occurs, hence the current can reach dangerous values ...

AC Fault Ride Through in MMC-Based HVDC Systems
IEEE Transactions on Power Delivery, 2022 VSC-HVDC systems are being increasingly employed in the power systems. The recently installed HVDC systems have a power capacity similar to traditional power plants. Hence, they are expected to have a similar behaviour as traditional synchronous generators during faults in AC grid, within their limits of course. Recent grid codes require HVDC converter

DC Fault Ride-Through Strategy Based on Overmodulation [PDF]
IOP Conference Series: Earth and Environmental Science, 2021 Abstract The hybrid modular multilevel converter (hybrid MMC) can realize DC fault ride-through based on the capability of overmodulation and can continue to output reactive power to AC side during the fault, which can speed up the recovery of DC grid power after the fault is cleared.
