a 1200 V SiC MOSFET, for example, increases only 20% over operating temperature compared with over 250% for a 1200 V silicon MOSFET [7], and in device modeling, the inversion layer mobility in SiC may be considered constant over the temperature range of 27 °C to 325 °C [8].
Silicon carbide mosfet maker Wolfspeed did a presentation on its 180kW electric vehicle motor drive – designed with NXP and Vepco – at virtual-PCIM this year. The three phase design is for permanent magnet motors, and is good for 15,000rpm and peaks above 97% efficient.
2011/9/12· Silicon carbide also has a thermal conductivity 2.8X higher than silicon, providing a much higher current density at a given junction temperature than a comparably-rated silicon device. With a bandgap that is approximately 3X wider than silicon, SiC devices also exhibit significantly lower leakage current at high temperature operation – by more than two orders of magnitude.
The less mature manufacture process limits the yield and the single die size of the SiC MOSFETs, which results a smaller current capability of a single SiC MOSFET die. Consequently, in high current appliion, the paralleled connections of SiC MOSFET dies are required.
