<p>The electronic transformer has a switch which converts an input voltage into a high frequency output voltage, a transformer (23-25) which converts the switch output voltage into a working voltage for the load and a short circuit stage (26,27). The short circuit stage short circuits the secondary side of the transformer to a reference potential (P) for AC current. The short circuit stage is connected to a centre tapping (30,31) of at least one transformer secondary winding (24,25).</p> |
