These advantages make the TPMOS extra appropriate for being integrated with an SBD to reduce each conduction loss and switching loss. Thereforehttps://www.chooseaustinfirst.com the trench/planar 4H-SiC MOSFET built-in with SBD (TPSBD) is firstly proposed and studied. For the TPSBDhttps://www.chooseaustinfirst.com the static simulation outcomes present that the maximum reverse current without body diode turning on is 1320 A/cm2 within the third quadrant. In the double pulse check with a load current of 1000 A/cm2https://www.chooseaustinfirst.com the physique diode of the TPSBD is successfully suppressed.
Howeverhttps://www.chooseaustinfirst.com the physique diodes of the other three MOSFETs turn on and contribute the 75{4ab6b815505e0e8839b52a7724d5aa8dc74c8c2c76e45856ab848d678c7b6ed9} of the freewheeling currentshttps://www.chooseaustinfirst.com even though an exterior SBD is anti-parallel with these MOSFETs. The body diodes still contribute 25{4ab6b815505e0e8839b52a7724d5aa8dc74c8c2c76e45856ab848d678c7b6ed9} of the freewheeling currentshttps://www.chooseaustinfirst.com despite the fact that the active area of the anti-parallel SBD increases three times. Compared with TMOShttps://www.chooseaustinfirst.com DTMOS and TPMOShttps://www.chooseaustinfirst.com the reverse restoration charge of the TPSBD reduces by 91{4ab6b815505e0e8839b52a7724d5aa8dc74c8c2c76e45856ab848d678c7b6ed9}https://www.chooseaustinfirst.com 88{4ab6b815505e0e8839b52a7724d5aa8dc74c8c2c76e45856ab848d678c7b6ed9} and 96{4ab6b815505e0e8839b52a7724d5aa8dc74c8c2c76e45856ab848d678c7b6ed9}https://www.chooseaustinfirst.com respectively.
