【Abstract】 A design analysis of maximizing the active cathode is executed,that an elaborate cathode mask pattern and an area-reduced junction termination are created.The technical specifications of ultra high voltage(UHV) thyristors are updated and more flexibly optimized acording to application requirements.The new generation thyristors of 6.3 kA/7.5 kV or 5.5 kA/8.5 kV are successfully manufactured and fully proved to be reliable devices for constructing a novel converter valve of ±800 kV/6.25 kA/10 GW or ±1 100 kV/5.5 kA/12.1 GW.更多还原
