Abstract: There is provided a controller for magnetic levitation equipment comprising a plurality of current source modules for connecting to at least one power supply for direct current, DC, and said current source modules comprising current channels for actuating coils of the magnetic levitation equipment, and a controller device connected to the current source modules by a control connection for controlling switching of electric current by the current source modules to the current channels. The current source modules combine discrete components for amplifying and switching electric current to the current channels into a single package. In this way, manufacturing and maintenance of the controller is facilitated, since manufacturing and maintenance may be based on the current source modules instead of discrete components, e.g. gate drivers, IGBTs, power mosfets and diodes.

Abstract: A control system for controlling a magnetic suspension system includes controllers each being configured to control one or more of magnetic actuators magnetically levitating an object. One of the controllers is configured to operate as a master controller and other one or ones of the controllers are configured to operate as one or more slave controllers. The master controller is communicatively connected with one or more digital data transfer links to the one or more slave controllers and configured to control operation of the one or more slave controllers. The control system makes it possible to implement a centralized control with separate controllers, and thereby without a need for a controller having a high number of controller current sources.

Abstract: This invention provides an electrolyte salt for use in an electrodeposition process for depositing Zirconium metal on a thin foil substrate. The prior art electrochemical process causes a reaction between a uranium substrate and ZrF4 species in the electrolyte that causes the formation of UFx at the substrate surface that prevents the formation of a dense uniform zirconium coating. This problem is solved by using an electrolyte salt in an electrodeposition process consisting of lithium fluoride (LiF) in a concentration ranging between about 11.5 molar percent and about 61 molar percent and one or more salts selected from the group consisting of sodium fluoride (NaF), potassium fluoride (KF), cesium fluoride (CsF), or cesium chloride (CsCL). Zirconium is added to the electrolyte salt through an addition of zirconium fluoride (ZrF4) in the range of about 1 to about 5 mass percent (w/w %). The Zr coating is of at least 98% pure Zr with a density of at least 98%.

Abstract: A control device (101) for controlling a magnetic levitation system includes a controller (103) for controlling one or more voltages directed to one or more windings of the magnetic levitation system on the basis of a deviation of a position of an object (108) to be levitated from a reference position so as to control a resultant magnetic force directed to the object. The controller selects, for each of temporally successive control periods, a control direction so that ability of the resultant magnetic force to decrease the deviation of the position is improved when the resultant magnetic force is changed in the selected control direction. Thereafter, the one or more voltages are selected in accordance with the selected control direction so as to decrease the deviation of the position by changing the resultant magnetic force. Thus, there is no need for nested control loops which are typically challenging to tune.
