Analysis of line-commutated converters during unbalanced operating conditions
IEEE Transactions on Energy Conversion, 1994In this paper, a method of analyzing the salient performance characteristics of line-commutated power converters during unbalanced operating conditions is presented. Simple analytical relationships are established which relate the negative-sequence component of AC current to the negative-sequence component of voltage. These results are verified using a

Sixth International Conference on AC and DC Power Transmission, 1996
Development of large-capacity, gate turn-off thyristors (GTOs) has led to a self-commutated power converter (SCC) system applicable to electric power transmission systems. During introduction of the SCC systems, a hybrid HVDC system composed of a conventional line-commutated converter (LCC) and the SCC was studied.

Digital firing control for line-commutated high power converters
Sixth International Conference on AC and DC Power Transmission, 1996Typical line-commutated high power converters for HV-AC systems are thyristor controlled reactors (TCR), thyristor switched capacitors (TSC), high voltage direct current transmission (HVDC) and rectifiers for DC arc furnaces. These high power converters require higher dynamics and higher quality of their control hardware than applications of smaller ...

Line frequency commutated voltage source converters for multiphase modular multilevel converters
2023Aspects are described for line frequency commutated voltage source converters for multiphase modular multilevel converters. A voltage source converter (VSC) capacitor voltage of a multiphase VSC of a multiphase power converter can be identified. The multiphase VSC can include a half-bridge circuit for each phase of the multiphase power converter.

Contactless circuit breaker protection for AC line commutated thyristor converter
IEEE CCECE2002. Canadian Conference on Electrical and Computer Engineering. Conference Proceedings (Cat. No.02CH37373), 2003Solid state power devices can be more easily damaged by load disturbances, faults and overcurrents. The AC line commutated high power thyristor converter is a reasonable power converter. It needs a fast acting short circuit protection against internal faults due to inverter commutation failure (flop) or faults in the DC line.
