Abstract:
1. A reactor arrangement comprising: a first alternating voltage terminal for receiving first alternating electrical current; a second alternating voltage terminal for receiving second alternating electrical current; a first direct voltage terminal; a second direct voltage terminal; a magnetic core element made of magnetically amplifying material; a first unidirectional electrical component on a first electrical current path from the first alternating voltage terminal to the first direct voltage terminal; a second unidirectional electrical component on a second electrical current path from the second direct voltage terminal to the first alternating voltage terminal; a third unidirectional electrical component on a third electrical current path from the second alternating voltage terminal to the first direct voltage terminal; a fourth unidirectional electrical component on a fourth electrical current path from the second direct voltage terminal to the second alternating voltage terminal; a first coil on the first electrical current path; a second coil on the second electrical current path; a third coil on the third electrical current path; and a fourth coil on the fourth electrical current path, wherein the first unidirectional electrical component and the second unidirectional electrical component are arranged to direct the first alternating electrical current to the first coil as a response to a situation in which the first alternating electrical current is positive, and to the second coil, as a response to a situation in which the first alternating electrical current is negative; the third unidirectional electrical component and the fourth unidirectional electrical component are arranged to direct the second alternating electrical current to the third coil as a response to a situation in which the second alternating electrical current is positive, and to the fourth coil, as a response to a situation in which the second alternating electrical current is negative; and the first coil, the second coil, the third coil, and the fourth coil are arranged to magnetize the magnetic core element in a same direction and to have mutual magnetic couplings.
