Abstract
The present invention relates to a switched-mode power supply comprising a transformer (T ) having an additional control winding (N ). This control winding (N ) forms part of an over power protection system by providing information relating to the line voltage V . Additionally, the control winding (N ) forms part of an over voltage protection system by monitoring the output voltage, V , of the switched-mode power supply. The sensing of V and the monitoring of V is performed in a time phased way so that the same control winding (N ) may be used to provide a plurality of information relating to the performance/status of the switched-mode power supply.
