Abstract: A system and method for seamless resource sharing among web applications bundled into a software suite are disclosed. The present disclosure addresses the problem of manually downloading and uploading a resource from one web application to another web application inside a unified system, using Drag & Drop or Copy & Paste using a clipboard. One or more resources can be shared by a user from a source web application. The meta information of the resource is shared with a Resource Sharing Server, and the network resource of the user machine is not used in the download and upload process. The clipboard used in the Copy & Paste functionality facilitates pasting the content copied by users across multiple web applications, different sessions, and different devices. While sharing the resources, the permissions of the sender and receiver on the shared resource are used to filter the original resource using a permission filter and share only that which is permitted.

Abstract: The invention provides a T-connected autotransformer for converting three-phase ac input voltages to nine phase shifted ac voltages feeding three sets of three-phase diode rectifier bridges. The nine phase shifted voltages are at an angle of +20 degree or ?20 degree with respect to the supply voltages and their magnitudes are essentially identical. The present design requires substantially fewer coils than other autotransformers for 18-pulse AC-DC converters, resulting in saving in space, volume, weight, size and cost of the converter. The magnetics requirement is only about 30% of the drive rating. The output voltage ratio can also be selected to give an average dc output from the proposed converter same as that of a conventional three-phase diode bridge rectifier. However, it is also possible to step up or step down the output voltage as required.
