Figure 117: Perform Slew Rate Analysis
The voltage (Purple) and current waveform (Yellow) are displayed along with a
differentiated math function waveform that shows the slew rate (White).
Max and Min measurements on the slew rate waveform are added and displayed.
Voltage slew rate: dV/dt = [V
(n)
– V
(n-1)
]/ [t
(n)
– t
(n-1)
], measures the slew rate of Vds
of the power device (MOSFET).
Current slew rate: dI/dt = [I
(n)
– I
(n-1)
]/ [t
(n)
– t
(n-1)
], measures the slew rate of Id of
the power device (MOSFET).
