Three-phase reactor for decoupling electrical power source of alternating current network for use in e.g. inverter, has magnetically conductive common mode rejection ratio compound provided between first and second conductive yokes

摘要

The reactor (1) has three magnetically conductive arms (9, 10, 11) arranged between first and second magnetically conductive yokes (3, 4). Each of the conductive arms is arranged around three electric coils (6, 7, 8). A magnetically conductive common mode rejection ratio (CMRR) compound (2) is provided between the first and second magnetically conductive yokes. A magnetic path is provided from the first yoke on the CMRR compound to the second yoke of a magnetic coupling of columns (12, 13).
