Efficiency vs. load

The active mode efficiency is defined as the average of the efficiencies measured in

different load conditions. These different load conditions are: 25%, 50%, 75% and 100% of

the maximum load. Table 8 reports the active mode efficiency calculated from the measured

values displayed inTable 7. For better visibility, the values of Table 8 are also plotted in

Figure 16

. Figure 17 reports the averaged efficiency value versus load (average is

measured considering the efficiency at different input voltage).
