Efficiency and no-load measurements

The efficiency of the converter has been measured in different load and line voltage

conditions.

According to the Energy Star average active mode testing efficiency method, the efficiency

measurements have been performed at 25%, 50% and 75% and 100% of the rated output

Table 4 and Table 5 show the results.
