6 Thermal map
In order to check the design reliability, a thermal mapping by means of an IR camera was
done. In Figure 38 the thermal measurements of the board, component side at nominal
input voltage, are shown. Some pointers visible in the image have been placed across key
components or components showing high temperature. The ambient temperature during
both measurements was 27 °C. It is possible to see that the PFC part has a different
temperature depending on the input mains.
