10.2 Test Setup
The following parameters and controls are available for executing the EN 61000-4-17 test:
Control / Field Description
Nominal DC voltage This is the rated nominal DC supply voltage to the EUT. Both a high
and low DC voltage range can be specified as well. When selected, the
test will run at the selected voltage levels. This can any combination of
nominal, high and low.
Line frequency This sets the nominal AC line frequency. The ripple frequency will be a
multiple of the AC Line frequency.
Output Select For three phase systems, the output select enables one of three
outputs or all three. The default is channel (phase) A.
EUT Test Levels The test levels used are determined by the EUT class. Available levels
are 2, 5, 10 or 15 %. A user defined test level from 0 to 25 % may be
set as well.
Ripple Frequency This fields sets the multiplier for the ripple frequency. Available settings
are 1, 2, 3 and 6. A user defined multiplier is available as well.
Test Time The default test time is 10 minutes. If more than one DC Voltage level
is selected, the test time increases with this amount for each selected
level. The test time can be set as low as 1 minute or as high as 9999
min.
Start Starts the EN 61000-4-14 test using the parameters set by the user.
Test progress is shown at the bottom of the window. The sequence
numbers shown correspond to those in the illustration.
Stop Aborts test in progress.
10.3 Test Sequence
The test sequence implemented by this test consists of the application of an AC ripple of specified peak to
peak value in percent of the DC voltage at a frequency determined by the multiplier times the AC Line
frequency for a set period of time.
The ripple waveform consists of a sinusoidal linear waveshape as shown below. The objective of this test is
to evaluate a product for immunity from such ripple.
