Test results and significant waveforms AN3065

The measured efficiency shown in Figure 9, measured according to the ES-2 requirements,
is very good at all load and line conditions. At full load it is always higher than 93%, making
this design suitable for high efficiency power supplies. The average efficiency, calculated
according to the ES-2 requirements, at different nominal mains voltages is shown in
Figure 10.
The measured output voltage at different line and static load conditions is shown in
Figure 11. As visible, the voltage is very stable over the entire input voltage and output load
range.
4.2 Inductor current in TM and L6563S THD optimizer
The following figures show the waveforms relevant to the inductor current at different voltage
mains. As visible in Figure 12 and 13 the peak inductor current waveform over a line half-
period follows the MULT (pin #3) at both input mains voltages and therefore the line current
