WebMar 8, 2007 · If there is more ringing on the gate than VGEM, stray circuit inductances probably need to be reduced, and/or the gate resistance should be increased to slow down the switching speed. In addition to the power circuit layout, gate drive circuit layout is critical in minimizing the effective gate drive loop area and resulting stray inductances. WebThe choice of gate resistor has a significant effect on the switching delay time. In general, the higher the resistor, the longer the delay time. It is recommended to measure the delay time with a dedicated gate resistor in the application. Figure 4 and Figure 5 show the typical graphs of switching time versus gate resistor.
