What are wide bandgap semiconductor and how can they help FACTS and HVDC? What problems does it solve?
For very high-power and high-voltage applications such as FACTS and HVDC, ABB’s silicon based StakPak IGBTs and Thyristors are setting the benchmark in overall performance. White bandgap devices such as SiC or GaN are very promising in low power applications – but not yet mature enough both technologically and commercially, to penetrated multi megawatt to gigawatt applications.
