Research Institution
The development of a novel high performance power module based on fast, ultra high voltage Thyristor-based SiC switch is proposed. Innovations proposed include: (a) development of a new type of Silicon Carbide Thyristor structure optimized for high pulsed currents; (b) Wire bond-less packages with extremely low parasitic inductance; (c) methods of series-parallel connection of large number of >15kV modules, that are relevant towards pulsed power and electric utility applications. Novel methods to use the proposed devices in pulse modulators are proposed. Relevant SiC fabrication experiments will be conducted in a semiconductor foundry to fabricate ultra high voltage SiC devices. Extensive test and reliability plan will be developed for evaluating devices for high pulse currents as well as trigger circuits. Power modules will be designed to have low parasitic inductance, high voltage stand-off capability and low thermal impedance. Finally, optimized bipolar devices will be fabricated and packaged in a power module optimized for a scalable design that can achieve up to 140 kV, 50 kA pulsed capability.
