Hi team,
My customer tried to increase Cgd / Cgs to limit the inrush current, but the improvement was less. Therefore, engineers turned to increase the gate resistance, 4 kOhm to 60 kOhm and found that the inrush current can be limited within the target range.
Can you comment that the solution has no problems or any potential risks? Thank you!
Schematic: Cgd/C8251= 1nF, Cgs/C8252= 47nF, Gate resistors/R8247 & R8248= 4.02k => 60.4k
Inrush current waveform: Ch1: input voltage, Ch2: gate, Ch3: source, Ch4: input current
The SOA of ACFET:
Best regards,
Sam Ting
