The plot shows the total efficiency of high-frequency PFC at different power levels tested in a climatic chamber at 50°C and an input voltage of 220 V. The curves are related to different SiC Schottky diodes tested in the circuit versus the Vishay device (light blue curve). The Vishay device shows overall good performance as aligned with major competitors. It is important to note that the efficiency gap among competitors is limited at 0.15%.
