Three-Phase AC–DC Converters 11-21
With these assumptions, the line voltage can be estimated by summing rectier’s voltage with volt-
age drop across inductors. e calculation of voltage drop across the inductance can be done by, as
described in previous section, dierentiation of current or estimation based on the power theory [6]:

In the case of lter-capacitor voltage estimation, calculations are realized in a similar way, but the recti-
er’s voltage is summed with only voltage drop across inductance L
