| Abstract |
The Field Controlled Thyristor (FCTh) has been recently introduced as an alternative switching device for potential applications at high power levels. Snubberless switching of clamped inductive loads at high speeds has been demonstrated previously. This paper is aimed at a detailed and independent experimental evaluation of the switching characteristics of a 10 A 2000 V FCTh under hard and soft switching operation conditions. Operating principles of the device are reviewed in brief, highlighting the drive requirements. Results of experimental tests include on-state and switching losses as well as switching times under hard switching and an overview of the device characteristics under quasi-resonant zero current and zero voltage switching. |
