Trace A represents the ripple voltage on C
BOOST
(200mV width).
Trace B represents the voltage perturbation due
to the Step-Up converter on the output (source of
the power Mosfet = Board power supply).
Traces 1 and 2 represent the same, but improved
thanks to the Step-Up Noise reduction RC.
5.2. Precision Enhancement
If the system needs accurate current limitation in
an environment subject to very wide temperature-
variations, a good way to compensate fluctuations
due to temperature variations is to use a CTN as
described in figure 13.
Figure 13 : Wide Temperature Variations
5.3. Temporisation
In some cases, it can be useful to let short current
peaks pass without reaction of the breaker,
though these are of higher value than the fixed
current limit.
This enables the Electronic Circuit Breaker to be-
have as a thermal disjonctor.
This behaviour can easily be given by adding an
RC constant as shown on figure 14.
