Figure 4. Efficiency input stage

Figure 4 shows the efficiency comparison implementing on board three different setting of

bridge rectification. No relevant difference have been highlighted using a standard diode

bridge (1 A or 0.5 A). The best efficiency has been captured using a bridge with four discrete

1A Schottky diodes, reaching even a gain about 1%.
