FILTRE PASSIF ET SYSTEME D'ALIMENTATION D'UN MOTEUR ELECTRIQUE COMPRENANT UN TEL FILTRE

摘要

The filter (20) has an electromagnetic coil (22) arranged in series with a conversion device e.g. three-phase voltage inverter (18), and an electric motor (12), and comprising an output terminal (30) adapted to be connected to the motor. Another electromagnetic coil (24) and a condenser (26) are connected in series with each other, and are arranged between the output terminal and an electric ground (32). A magnetic core (34) couples the electromagnetic coils for an alternating current phase. The electromagnetic coils are wound around the magnetic core. An independent claim is also included for a power supply system of an electric motor.
