High Voltage, Volume 10, Issue 3, Page 546-554, June 2025.Abstract Commutation failure (CF) is an inherent problem faced by line commutated converter high voltage direct current (LCC‐HVDC) technology. To completely solve the problem of CF, we have proposed a novel hybrid commutated converter (HCC) technology based on reverse blocking integrated gate commutated thyristor, which can utilise two methods for ...

Design of cooling structure improvement of hybrid commutated converter valve
High Voltage, Volume 10, Issue 3, Page 570-580, June 2025.Abstract This paper presents a thermal management framework for 120 kV hybrid commutated converter (HCC) valves, addressing critical cooling challenges in multi‐hundred‐MW power conversion systems. Power loss calculations under rated (1.0 p.u.) and overload (1.2 p.u.) conditions demonstrate that HCC valves achieve comparable loss levels to line ...
