DER-10
13 Conducted EMI
EMI was tested at room temperature, during normal operation, playing a DVD. Note the
lower EMI, especially with output grounded, in spite of having no common mode choke,
no Y-cap and no X-cap. The excellent EMI is possible with TinySwitch-II because of its
built-in frequency jitter. Note that in normal use, the DVD player is connected to the TV,
and the TV chassis is grounded through the antenna wire or cable. Therefore the EMI
setup that is representative of the actual application is with the output grounded back to
the LISN ground plug.
