摘要： The invention relates to an EMI filter (1) comprising a choke (2). The choke (2) has a magnetic inner core (9), a magnetic outer core (10), and at least one conductor pair (11) comprising two electrically conductive conductors (12a, 12b). In the choke (2), the inner core (9), the outer core (10), and the respective conductors (12a, 12b) extend along a longitudinal central axis (LA). The inner core (9) is arranged in the outer core (10), and the respective conductors (12a, 12b) are arranged between the inner core (9) and the outer core (10). The respective conductors (12a, 12b) are arranged spaced apart from one another in a circumferential direction, and the inner core (9) and the outer core (10) are arranged spaced apart from one another in the radial direction. A gap (14) is thus in each case formed between the inner ring (9), the outer ring (10), and the respective conductors (12a, 12b), which are adjacent in the circumferential direction.
The invention also relates to an inverter comprising the EMI filter (1) according to the invention.
