PULSE CAPACITOR APPLICATIONS
As mentioned earlier, the voltage drop in a circuit is critical
as the circuit will not operate below a certain cut-off voltage.
There are two sources of voltage drop (ΔV) which occur, the
first ΔV
(ESR) and the second, called the capacitive drop, is ΔV
From Ohm’s law,
Let us say that the instantaneous starting voltage is Vo, or
voltage for the circuit from where the voltage drops. If the
capacitor has an ESR of 100 milliOhms and the current is 1
amp,
On demand, during the discharge mode, the voltage V = Vo
- ΔV
The second voltage drop is because of the capacitance.
This is shown in the equation as a linear function because of
simplicity. Simply put,
Hence, ΔV
I x dt/C. This formula states that the larger the capacitance
value the lower the voltage drop. Compared to a Ta capacitor

needed. If the current pulse itself is 1 amp, the current pulse
width is 1 second, and the capacitance is 10 millifarads, the
ΔV
is out of the range of BestCap
becomes narrower, say 10 milli-seconds, and the capaci-
tance is 100 millifarads, the ΔV
= 0.1 volt or 100 milli-volts. This shows the advantage of the
large capacitance and hence the term “pulse” capacitor.
The specific power – specific energy graphs are used in the
battery industry to compare competitive products. As the dt
becomes smaller i.e.100 milliseconds, 10 milliseconds and
then 1 millisecond, our estimates show that the specific
power for the BestCap
competitors because of our choice of internal materials
chemistry.
Conclusion: we now clearly show that BestCap
advantage over competitors for short current pulse whose
widths are smaller than a few hundred milliseconds.
