Switching loss analysis (SW.Loss):
Switching loss analysis
(SW.Loss)::
The total loss and the switching loss can be measured.
Items such as power waveforms and measured values can be
displayed, and statistics can be computed.
The items whose switching losses can be measured automatically
are listed below.
Wp, Wp+, Wp-, Abs.Wp, P, P+, P-, Abs.P, and Z
Safe Operating Area
(SOA)::
An X-Y display can be created with voltage input plotted on the
X-axis and current input plotted on the Y-axis.
Harmonic Analysis
(Harmonics)::
Simple comparisons can be made between the harmonics and the
following limits.
IEC 61000-3-2 Ed. 2.2, “Electromagnetic compatibility (EMC) - Part
3-2: Limits - Limits for harmonic current emissions (equipment input
EN61000-3-2(2000)
IEC 61000-4-7 Ed. 2
Joule Integral (I
2
t):: Items such as Joule integral waveforms and measured values can
be displayed, and statistics can be computed.
The items whose Joule integral can be measured automatically are
listed below.
I
2
t
Trend display:: The change over time of the measured waveform parameters in
each period can be displayed in trends.
History search: You can search through the history for the power supply analysis
items just as you can for the standard measurement items.
Saving results of harmonic computations:: The results of harmonic computations can be saved
to CSV files.
Also, during power supply analysis, the time difference between the voltage and current
waveforms can be automatically deskewed.
For automatic deskewing to be performed, the voltage and current signals of the deskew signal
source (701935; sold separately) must be connected through probes to CH1 and CH2 (or CH3
and CH4), respectively.
For information about the deskew range, see “Deskewing” in this section.
1 On models with the Ethernet option.
2 Measured over the entire measurement range when the cycle mode is set to OFF
, measured within a period extracted from
the measurement range when the cycle mode is set to ON.
