Mechanism and Prevention of Commutation Failure in LCC-HVDC Caused by Sending End AC Faults
IEEE Transactions on Power Delivery, 2021This letter analyzes the mechanism of commutation failures (CFs) caused by sending end AC faults. It is founded that the dc impulse current after fault clearance is the direct reason of CF occurring under nonserious sending end AC faults, and the ...

A Commutation Error Compensation Strategy for High-Speed Brushless DC Drive Based on Adaline Filter
IEEE transactions on industrial electronics (1982. Print), 2021The commutation errors undermine the control performance of a brushless direct current (BLdc) drive especially at high-speed operation. In this article, a novel commutation error compensation strategy for BLdc drive that eliminates the phase deviation ...
