WebSurge-energy and overvoltage ruggedness of power devices are desired in many power applications. For the GaN high-electron-mobility transistor (HEMT), a device without avalanche capability, its surge-energy and overvoltage ruggedness are both determined by its transient breakdown voltage (BV), which was recently found to be dynamic (i.e., time- …
WebAB - This work studies the dynamic breakdown voltage (BV) and overvoltage margin of a 650-V-rated commercial GaN power HEMT in hard switching. The dynamic BV measured in the hard switching circuits is over 1.4 kV, being 450 V higher than the static BV measured in the quasi-static I-V sweep. The device can survive at least 1 million hard ... WebThe change of BV with FSW can be explained by the time-dependent electron trapping and the impacted dynamic BV of GaN HEMTs. In HD-GIT, an additional p-GaN is electrically connected to the drain metal, holes are injected from the drain under high VDS, which neutralize the acceptor traps in the GaN buffer and alleviate the peak E-field at the ...
