TIDM-1000: Figure 6 DC Voltage Control Model

Part Number: TIDM-1000


I have a question on the Design Guide TIDM-1000 of Vienna Rectifier-Based, Three-Phase Power Factor Correction (PFC) Reference Design Using C2000 MCU.

Specifically it is on Figure 6 DC Voltage Control Model on page 10.

It seems that, with reference to Figure 6, the current reference ILi* is eventually given as follows:

ILi* = Po* x Vbus_avg/3VacRMS

I wonder how the above-mentioned equation is analytically valid.

Thank you for your advice.

With regards,
