Abstract: A device (24) for controlling a magnetic bearing (22) includes an axis with two electromagnets (26, 28) diametrically opposed. The device (24) includes two power converters per axis of the magnetic bearing. Each power converter supplies one different electromagnet. The device includes eight power devices (40, 42, 44, 46, 48, 50, 52, 54) arranged in a first line (88) and a second line (90). Each of the first and second lines includes four power devices. A first set of four power devices (40, 42, 44, 46) are connected together to form a first power converter. A second set of four power devices (48, 50, 52, 54) are connected together to form a second power converter. Each of the first and second lines (88, 90) includes two power devices (40, 42, 44, 46) of the first set and two power devices (48, 50, 52, 54) of the second set.
