Abstract

The invention relates to a method for common-mode suppression of interference in frequency changers (1) used to regulate the power flow between two different electrical systems at low loss whereby one system is a direct current system. The frequency converter produces a common-mode parasitic voltage (21) which occurs between the reference potentials of both systems. The reference potential of the direct current system is present at terminal (16). The reference potential of the other system, preferably the neutral potential of a three-phase current system can be found at terminal (5). The primary winding (37) of the interference suppression transformer (31) is connected to terminals (5) and (16).The secondary windings (36,38) are mounted in the positive and negative supply line of the direct current system or are connected to frequency changer terminals (9,10) on the d.c. side and terminals (32,33) of the direct current system. The common-mode parasitic voltage (21) occurring at winding (37) is also present at the secondary windings (36, 38) and is compensated so that no alternating voltage can be found between a suitable reference potential of the direct current system and the potential at terminal (5) which is preferably an earth potential.
