Abstract (en)
The invention relates to a reactor arrangement that comprises a magnetic core structure (101), a winding (102), and a permanent magnet (103, 103a). The permanent magnet generates a biasing magnetic flux component into a first part (104) and into a second part (105) of the magnetic core structure. The winding magnetizes the first part of the magnetic core structure in a direction opposite to the biasing magnetic flux component when electrical current is positive and the second part of the magnetic core structure in a direction opposite to the biasing magnetic flux component when the electrical current is negative. Hence, the biasing magnetic flux component can be utilized for locally relieving magnetic saturation of the magnetic core structure during both negative and positive temporal portions of the electrical current. Therefore, the size and the weight of the magnetic core structure can be reduced.
