An EMI filter for an inverter may include a choke including a magnetic inner core, a magnetic outer core, and at least one conductor pair. The at least one conductor pair may include an electrically conductive positive conductor and an electrically conductive negative conductor. The inner core, the outer core, the positive conductor, and the negative conductor may extend along a longitudinal central axis of the choke. The inner core may be arranged in the outer core. The positive conductor and the negative conductor may be arranged between the inner core and the outer core. The positive conductor and the negative conductor may be arranged spaced apart from one another in a circumferential direction extending around the longitudinal central axis. A gap may be formed between the inner core, the outer core, the positive conductor, and the negative conductor, which are adjacent in the circumferential direction.

An operating state monitoring device for monitoring a connecting cable, the device may include a connecting cable and at least two Hall sensors. The connecting cable may have at least two electroconductive conductors that extend along a longitudinal central axis, and through each of the conductors current flows or currant can flow by forming a magnetic field. The at least two Hall sensors may be configured to detect magnetic fields and output measuring signals based on detected magnetic fields. The device may have a number of Hall sensors that is identical to the number of conductions. A single Hall sensor may be arranged proximate each conductor via direct contract or indirect contact.
