Subsequently, the external HS gate resistor becomes 2.2
Ω, while the other components
remain unchanged (“Configuration 2”). A further reduction of the phase node spike is
achieved (30.1 V). In Figure 50, the waveforms at full load conditions are reported.
Finally, the snubber resistor value is decreased from 1.8
Ω to 1 Ω, to emphasize the CSNUB
effect (“Configuration 3”). The gate resistors are unmodified (Figure 51).
Figure 50.
RG,HS(EXT) = 2.2 Ω - RG,HS(EXT) = 1.8 Ω/ original snubber waveforms @ 20 A
