Load Line
Inductance
Considerations When using the PEL-3000 load generator,
voltage drop and voltage generated due to load
line inductance and current change must be
taken into account. Extreme changes in voltage
may exceed the minimum or maximum voltage
limits. Exceeding the maximum voltage limit
may damage the PEL-3000.
To determine the voltage generated, the
following equation can be used.
E = L x (∆ I / ∆ T)
E= voltage generated
L=load line inductance
∆ I= change of current (A)
∆ T= time (us)
Load line inductance (L) can be approximated
as 1uH per 1 meter of wire. (∆ I / ∆ T) is the
slew rate in A/us.
