Abstract: The present disclosure relates to a power conversion system comprising a transformer comprising first, second, and third inductive coupling elements, a first power supply arranged to provide a voltage across the first coupling element, a second power supply arranged to provide a voltage across the second coupling element, an output arranged to receive a voltage from the third coupling element. In use, the voltage across the first coupling element and the voltage across the second coupling element are arranged to induce a voltage in the third coupling element. The system also comprises a control arrangement arranged to independently control the operation of the first and second power supplies.

Abstract: A method for controlling the temperature of a component is disclosed. The component is part of a drive configured to drive an electrical machine via an electrically conductive member. The method comprises determining a value of an attribute of the electrically conductive member; configuring a model to calculate the temperature of the component, the model being configured based on the determined value of the attribute of the electrically conductive member; using the model to calculate the temperature of the component; and if the calculated temperature of the component does not meet a predetermined temperature condition, issuing a command to control the operation of the drive such that the temperature of the component is changed to meet the predetermined temperature condition.

Abstract: The invention relates to an enclosure 12. The enclosure 12 disclosed herein is arranged to house a heat generating component and comprises a top face, a rear face and a first side face. At least one of the first side face or the rear face comprises a substantially continuous portion and a venting portion 20. The venting portion 20 has at least one vent opening to allow air to be vented from within the enclosure 12. The venting portion 20 is recessed with respect to the substantially continuous portion of the respective face.
