(2) Calculation of harmonic current
Usually, calculate the harmonic current according to the Sub-table 3 "Three-phase bridge rectifier
with the smoothing capacitor" in Table 2 of the Guideline's Appendix. Table B.5 lists the contents of
the Sub-table 3.

- ACR: 3%
- DCR: Accumulated energy equal to 0.08 to 0.15 ms (100% load conversion)
- Smoothing capacitor: Accumulated energy equal to 15 to 30 ms (100% load conversion)
- Load: 100%
Calculate the harmonic current of each degree using the following equation:
