Thermal map
In order to check the design reliability, a thermal mapping by means of an IR camera was
done. Here below the thermal measures of the board, component side, at nominal input
voltage are shown. Some pointers visible on the pictures have been placed across key
components or components showing high temperature. The ambient temperature during
both measurements was 27 °C. We note that the PFC part has a different temperature
depending on the input mains, while the components of the resonant stage are working at
a temperature independent of the mains input voltage.
