Design of cooling structure improvement of hybrid commutated converter valve
Published 2025-06-01“…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 commutated converter counterparts while enabling active turn‐off control. …”
