The inductive or reactive reactance (XL) dof the smoothing choke can be calculated with the inductance of the choke (L) and the mains frquency (fmains): XL = ω x L = 2Pi x fmains x L The voltage drop (Uk) of the smoothing choke can be calculated with the rated current (IN) and the inductive reactance of the choke (XL)for 1-phase smoothing coils: Uk = IN x XLfor 3-phase smoothing coils: Uk = IN x XL √3 Example: Calculation of the voltage drop (Uk) of an one-phase smoothing coil with an inductance of L = 0,3 mH, a current of I = 100 A and a rated voltage of 230 V at f = 50 Hz: Reactance: XL = ω x L = 2Pi x 50 Hz x 0,3 mH = 0,094 ΩVoltage drop: Uk = IN x XL = 100 A x 0,094 Ω = 9,4 Vor given as percentage to mains voltage: Uk% = Uk / Umains = 9,4 / 230 = 4% In an american net with U = 110 V and f = 60 Hz the choke acts as following:Reactance: XL = ω x L = 2Pi x 60 Hz x 0,3 mH = 0,113 ΩVoltage drop: Uk = IN x XL = 100 A x 0,113 Ω = 11,3 Vor given as percentage to mains voltage: Uk% = Uk / Umains = 11,3 / 110 = 10,2% This means the same choke will have more than twice the Uk%, if operated in an american net. Tauscher chokes are calculated to have a small Uk%. Especially cut cores and cores made of amorphous and nanocrystalline materials have a small Uk% and thus low losses and a very good attenuation of harmonics.
