ABSTRACT:
A frequency changer having parallel partial frequency changers with a dc circuit has chokes that impress dc currents. These chokes are magnetically coupled to each other such that the change of a dc current in one of the partial frequency changers causes a corresponding change of the dc currents in the parallel partial frequency changer in the sense of a lead control. In a frequency changer constructed with an even number of partial frequency changers, the individual chokes can be coupled such that the magnetic dc fluxes in the coupling caused by the dc currents in the chokes are compensated.
