An EMC Case
Study
Top
Hex was approached by a client who was unable to get
their industrial machinery through the EMC tests. Despite
spending a large amount of money, their controller would
operate erratically during the tests.
We identified very quickly that the
design of their existing controller was the problem.
Attempting to correct these design flaws by fitting
expensive, external components was ineffective. Top Hex
has designed a brand new controller taking care to ensure
that adequate filtering was fitted to the circuit board
and also that the layout and tracking was optimised to
reduce the possibility of any EMC issues. The controller
was taken to TS for testing and passed with flying
colours, with only one inductor value needing to be
changed.
George Vassila of ETS had
the following comment to make, “When a product fails
EMC, the remedial measures taken by the manufacturer can
be time consuming and extremely expensive. Manufacturers
can avoid such undesirable situations by ensuring that
EMC compliance is considered at the design and
development stage. Applying suppression, filtering and
screening to contain problems at source is by far the
most cost-effective way of dealing with the EMC problems.”
