Light controlled (super) cascode, LC(S)C, a power device with optical turn-on and -off
摘要： The proposed light-controlled cascode is a power electronic device (or circuitry) which can be turned-on and -o? by optical excitation. In contrast to the light-triggered thyristor, which can optically be turned-on but not -o?, the proposed device allows optical turn-on and -o?. Also, it allows a scalability of the blocking voltage by the extension to a light-controlled supercascode [1] which is also shown. After a brief theoretical consideration experimental set-ups will be presented and measurements are shown. Due to the di?culty to buy appropriate devices required for the experimental set-ups some compromises were necessary. Therefore, these ?rst experiments show a very slow switching behaviour. However, this could become speeded up by an optimized photodiode made from wide band gap semiconductor material. In spite of these compromises pulses with a power of 1 kW were turned-on and – o? by the experimental set-up. However, this device is far away from being ready for series production but the feasibility is demonstrated and the potentials are shown.

Recent Developments Accelerating SiC Adoption
摘要： The benefits of SiC devices for use in power electronics has been long understood, and over 25 years of sustained development in materials and devices has brought adoption to a tipping point [1,15]. It takes the confluence of many separate developments to build the necessary momentum for accelerated adoption, and we will examine these factors.
