“…Several SC modes are known to exist in arm SC of a bridge inverter. [17][18][19][20] Occurrence of arm SC is illustrated in Figure 8. SC-type1 in Figure 8A is a SC mode that occurs when DU transits from OFF to ON while the opposite arm is already shorted.…”

This paper proposes methodology and gate drive circuit that can immediately detect short-circuit (SC) of multiparalleled SiC-MOSFETs even under current imbalance condition. Proposed method detects SC current using an integration circuit that can sense di/dt. The detection level of SC current can be adjusted to a desired value regardless of the number of SiC-MOSFETs connected in parallel. The effectiveness of the proposed approach was experimentally validated for four-paralleled SiC-MOSFETs under extreme current imbalance in SC condition. SC was detected within 0.5 μs and all SiC-MOSFETs were protected without destruction at most 2.2 μs after the onset of SC, for all types of SC 1, 2, and 3.

“…This routine test is also known as type I short‐circuit turn‐off test [16], which is to verify that IGBT is able to turn off the short circuit current if shoot‐through happens across the DC‐link capacitor. The test circuit is shown in Fig.…”
