Pulse current measurement

PFX2011

In pulse current measurement, each pulse current is measured and the average cur-
rent is calculated over a unit time.

IMn: Measured value of each pulse current
Tn: Time width of each pulse
Tave: Unit time for averaging (

xed to 500 ms)

Below is an explanation using an actual waveform.
Fig. A-9 is an example for a pulse waveform with a pulse time width that is shorter

than the unit time for averaging.
In this case, the average current is derived by summing the product of the measured

pulse current and the pulse time width until the unit time is reached (numerator of

Equation 1). When the unit time is reached, the sum is divided by the unit time to

derive the average current.

Fig. A-9

Averaging Example 1 of Pulse Current Measurement

Fig. A-10 is an example for a pulse waveform with a pulse time width that is longer

than or approximately the equal as the unit time for averaging. Similar to Fig. A-9,

the measured value of the current that

ows during the unit time for averaging is

used to calculate the average current.

Fig. A-10

Averaging Example 2 of Pulse Current Measurement

Average current =

IM1 • T1 + IM2 • T2 + IM3 • T3 + IM4 • T4
