TIDUE53I march 2018 – july 2023 TMS320F28P550SJ , TMS320F28P559SJ-Q1
This section shows the results obtained from the power analyzer as the load is slowly increased to 3.2 kW. The Figure 3-46 shows the steady state performance of PFC at 3.2 kW output power. Scope signals: Channel 1 - AC voltage (blue), Channel 2 - DC link voltage (light green), Channel 3 - AC current (dark green).
The results in Figure 3-46 are captured at 50 Hz but these can be verified at 60 Hz as well.
Figure 3-47 shows power key efficiency and THD figures captured at 3.2 kW.
