CONVERTER CELL ARRANGEMENT WITH COOLING SYSTEM

A converter valve arrangement is disclosed, including a converter cell, a first and second semiconductor switch element, a container and a two-phase cooling system including at least one evaporator arranged in thermal contact with the semiconductor switch elements and to at least partly evaporate a dielectric working fluid. The two-phase cooling system and the converter cell are arranged within the container, and a fluid return line is arranged to receive a two-phase flow from the at least one evaporator. During operation, the converter valve arrangement may include an electrically critical region between the container and the converter cell, and the two-phase cooling system is arranged to generate a single-phase flow including only a gas phase or a liquid phase of the dielectric working fluid from the two-phase flow received by the fluid return line, and to convey the single-phase flow through the electrically critical region. 公开了种变换器阀装置，包括变换器单元、第和第二半导体开关元件、容器和两相冷却系统，所述两相冷却系统包括被布置为与所述半导体开关元件热接触并且至少部分地蒸发介电工作流
