A Novel Sub-Module-Based Line-Commutated Converter That Is Actively Resistant to Commutation Failure
ActuatorsTo improve the ability of line-commutated converters (LCCs) to resist commutation failure (CF) when a fault occurs on the AC side, a novel sub-module-based LCC topology actively resistant to CF is proposed in this paper.

Affordable and Clean Energy: CO2 Emissions, Resilience and Inequality
Sustainable Development, EarlyView.ABSTRACT Sustainable development means building the resilience of both people and the planet. It includes implementing strategies which reduce emissions while also enabling more vulnerable households to transition to clean and affordable energy. This paper examines household CO2 emissions in Ireland to highlight those who emit most and least in key ...

Methods to Prevent Commutation Failures in HVDC Systems
B&H Electrical EngineeringAbstract Commutation failure (CF) is the main fault type in HVDC (High voltage direct current) system with line commuted converter. So, Commutation faults are the main disadvantages of line commutated converter HVDC systems. There are some situations that cause the fault in these types of faults that occur in thyristor valve ...
