11.5 Line Transient Response
In the figures shown below, signal averaging was used to better enable viewing the load
transient response. The oscilloscope was triggered using the load current step as a
trigger source. Since the output switching and line frequency occur essentially at random
with respect to the load transient, contributions to the output ripple from these sources
will average out, leaving the contribution only from the load step response.
