Patent ID: 7019990

Claim:
A converter with a damping mechanism for preventing resonances, comprising: a rectifier; an inverter; and an intermediate circuit which connects said rectifier to said inverter, said intermediate circuit comprising: a first conductor connected to a first potential; a second conductor connected to a second potential that is different than said first potential; a current-compensated choke looped into said first conductor and said second conductor, said current-compensated choke comprising: a first winding; and a second winding, wherein a first current flowing from said rectifier to said inverter flows through said first winding and a second current flowing back from said inverter to said rectifier flows through said second winding, wherein said first winding and said second winding are wound on a common core and said first winding and said second winding are arranged in such a way that magnetic fields of alternatingly arranged areas of said first winding and said second winding already cancel each other out before contributing to a magnetization of said common core.
