Figure 7. Inductive Switching Measurements
SWITCHING TIMES NOTE
In resistive switching circuits, rise, fall, and storage times
have been defined and apply to both current and voltage
waveforms since they are in phase. However, for inductive
loads which are common to SWITCHMODE power supplies
and hammer drivers, current and voltage waveforms are not
in phase. Therefore, separate measurements must be made
on each waveform to determine the total switching time. For
this reason, the following new terms have been defined.
tsv = Voltage Storage Time, 90% IB1 to 10% Vclamp
trv = Voltage Rise Time, 10 – 90% Vclamp
tfi = Current Fall Time, 90 – 10% IC
tti = Current Tail, 10 – 2% IC
tc = Crossover Time, 10% Vclamp to 10% IC
An enlarged portion of the turn–off waveforms is shown in
Figure 7 to aid in the visual identity of these terms.
