INTERFERENCE CURRENT COMPENSATION METHOD AND INTERFERENCE CURRENT COMPENSATION DEVICE FOR ELECTRICAL SYSTEMS

摘要

PPROBLEM TO BE SOLVED: To provide a method and a device for an electrical system capable of significantly suppressing an unwanted alternating current. PSOLUTION: An electrical system includes a voltage source 2 and a serial circuit including an inductance L and a capacitance C connected in parallel with the voltage source 2 via a conductor. The inductance L and the capacitance C are connected in series via a conductor. The conductor for connecting the voltage source 2 to the series circuit including the capacitance C and the inductance L or the conductor in the series circuit including the capacitance C and the inductance L is surrounded by a ring 3. The ring can be magnetized by an air gap of an interference current compensation device 1. As a result of magnetization of the ring 3 by a magnetizing coil 4 of the interference current compensation device 1, a compensation voltage USBK/SBis applied to the conductor for connecting the voltage source 2 to the series circuit including the capacitance C and the inductance L or the conductor in the series circuit including the capacitance C and the inductance L. The interference current compensation device 1 is also identified. PCOPYRIGHT: (C)2010,JPO&INPIT
