  • High-voltage direct current - Wikipedia

    A high-voltage, direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems. Most HVDC links use voltages between 100 kV and 800 kV.

  • Efficient and Reliable High Voltage Switching | Mouser

    Device Concept and ControlDevice CharacteristicsExperimental ResultsConclusionThe choice of device concept is crucial both in terms of reliability as well as expected performance in the application. A SiC MOSFET or JFET are devices with very similar device characteristics, both able to “transfer” the unipolar fast switching performance well known from Si super-junction MOSFETs up to 1200V blocking voltage. When it comes to technology maturity the MOSFET and JFET have though quite different merits. The main objective for us is to benefit from the proven robustness of our diode process line and avoid process concepts that are not yet thoroughly tested in the field. In this respect the MOSFET lacks maturity compared to a JFET. Mainly because the gate oxide process even if intrinsic reliability and threshold voltage stability is demonstrated introduces a failure risk due to the relatively high extrinsic defect density of the SiC material system. Effective screening strategies as a countermeasure to improve the quality have to be developed and proven. Excluding th...
