Figure 19. Efficiency comparison at different power level

The improvement in terms of efficiency is negligible at lower power levels, but it becomes

significant when the power level increases. The efficiency improvement in the demo board

at maximum power level (2 kW) achieves a highly significant value of 0.32%.

Figure 20. Efficiency comparison at different power level

From a thermal point of view, the temperature gap is already significant at low power levels

and reaches 20°C at the maximum load.
