    摘要： A drive system for an electrical load such as an electric motor or generator comprises a PWM converter and a controller therefore. A signal indicative of a condition of the converter outpost is used in a controller to drive an optimal value of PWM switching frequency based on a load characteristic that is used to control the pulse switching frequency. The system takes account of the overall system in deriving an efficient PWM switching frequency.

    摘要： A latch mechanism is provided comprising a latch and a cover arranged for attachment to the latch. The latch includes a latch body and a projection extending therefrom wherein, when the latch and cover are attached to one another, the projection extends from an inner surface of the cover. The latch mechanism further comprises a docking area located on a device, the docking area being arranged to receive the latch such that the cover may be securely fixed to the device. When the cover is placed over the docking area, a sliding movement of the cover causes actuation of the latch to secure the cover to the docking area. When the cover is secured in the docking area, further sliding movement of the cover is prevented.

    摘要： 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.

    摘要： A drive unit for housing components of a drive system for an electrical machine, such as an electric motor, comprises a cabinet having opposed first and second relatively narrow faces and a wide face between them. An interface for inputting and deriving data is mounted on a bracket to the unit and faces in the same direction as the wide face. The unit can be installed conveniently in situations in which depth is limited, while at the same time enabling the drive unit to be programmed and set in a convenient way.
