The power factor (PF) and the total harmonic distortion (THD) have also been measured
and the results are reported in
half load remains close to unity throughout the input voltage mains range, while when the
circuit is delivering 70 W it decreases at a high mains range. THD is low, remaining within
20% at the maximum input voltage.
The converter’s efficiency reported in
At full load, it is always significantly higher than 90%, making this design suitable for high-
efficiency power supplies.
The measured output voltage variation at different line and load conditions is reported in

the voltage is perfectly stable over the entire input voltage range. At 265 Vac and light load,
there is a negligible deviation of 1 V due to the intervention of the burst mode function.
