Switching Loss Analysis of SiC-MOSFET based on Stray Inductance Scaling ...

WebMOSFET. This variation in drain voltage is supported across stray inductances between the MOSFET dice. This sudden imbalance excites the oscillation of a resistive-inductive-capacitive (RLC) tank circuit involving the capacitances of each MOSFET die, the parasitic inductances in their interconnections, and the gate resistances. WebThere is virtually no source inductance in DirectFET, and the complete access to the source side of MOSFET enables the driver connection to the MOSFET gate and source terminals without including any PCB stray inductance in the high current path, as shown in Figure 2(b). Therefore, the high frequency switching performance of DirectFET is rolling hills shopping center torrance https://smallvilletravel.com
