This paper proposes a joint limiting control strategy for suppressing DC fault current and arm current in modular multilevel converter-based high-voltage direct current (MMC-HVDC) systems, which ...

The semiconductor switching of traction inverters produces a current ripple overlaying the dc current in the high-voltage dc bus of an electric vehicle (EV). Recent studies show that a current ripple ...

Link copied to clipboard DC 33 made concessions in 1992. Decades of resentment since led to Philadelphia’s current city worker strike. Many AFSCME DC 33 members have been itching for the union to take ...
