A Simple Multifunctional DC Chopper for Fault Ride-Through Capacity Enhancement of a DFIG

IEEE transactions on power electronics
Generally, crowbar circuits and dc choppers are employed to prevent rotor-side converter overcurrent and dc-link overvoltage, respectively, during the fault ride-through (FRT) process in doubly fed induction generators (DFIGs).

A Protection-Interoperable Fault Ride-Through Control for Grid-Forming Inverters

IEEE transactions on industrial electronics (1982. Print)
Differing from synchronous generators (SGs), grid-forming inverter-based resources (GFM-IBRs) exhibit rapid variations in their output impedances during transmission line faults due to the overcurrent limitation.
