MOSFET vs JFET JFETs can only be operated in thedepletion modewhereas MOSFETs can be operated in either depletion or inenhancement mode. In a JFET, if the gate is forward biased, excess- carrier injunction occurs and the gate current is substantial. Thus channel conductance is enhanced to some...

A 1200V SiC JFET is compared with a 600V Si MOSFET and a Si CoolMOS based on a full-bridge parallel resonant converter. With the maximum allowable junction temperature, the converters are designed and compared with maximum power and frequency. The advantages and disadvantages of the SiC JFET ...
The influence of the buffer layer and the gate voltage on the JFET on-state/breakdown performance is carefully investigated. The study concludes with a mixed-mode simulation of the transient behaviour of a 1.2 kV SiC JFET鈥揝ilicon MOSFET pair in a CASCODE configuration as a viable alternative...
MOSFET (Si), MOSFET (SiC), IGBT(Si) and JFET(SiC) were examined, each of them worked with either Si or SiC freewheeling diode. To ensure steady power loss measurement conditions the tests were carried out in the same measurement system in settled conditions. Simulation analysis resemble the...
The 4H-SiC JFET showed a very predictable, well understood temperature dependent characteristics, because current conduction depends on drift of electrons in the bulk regions, which is not restricted by traps in the MOS interface or pn junctions. However, in a 4H-SiC DMOSFET, electrons must ...
