Loss optimizing low power 50 Hz transformers intended for AC/DC standby power supplies
This paper presents the measured efficiency on selected low power conventional 50 Hz/230 V-AC transformers. The small transformers are intended for use in 1 W@5 V-DC series- or buck-regulated power supplies for standby purposes. The measured efficiency is compared for cheap off-the-self transformer and for some which are optimized for a lower no-load loss.
The optimization is done by simple and low cost means.
