After the V_CC capacitor C60 is charged, the converter starts up, supplying the LLC and PFC stage. Here V_IN was 115 VAC and the frequency was 400 Hz. The screenshots in Figure 3-16 through Figure 3-18 were taken, in no-load condition, 8-A and 13-A load.

Figure 3-16 No Load (C2: V_PFC, C4: V_OUT, C3: I_IN)

Figure 3-18 13-A Load (C2: V_PFC, C4: V_OUT, C3: I_IN)

Figure 3-17 8-A Load (C2: V_PFC, C4: V_OUT, C3: I_IN)
