Power electronics transformer technology exploration and application share



Power electronics transformer is drawing wide attention from both industry and academia. However, there are still numerous problems when pushing power electronics transformer into practical use. This report presents the development of 10kV/1MVA power electronics transformer prototype. The detailed design on topology, key component and control system is introduced. Moreover, to replace the conventional power converting method in PV and micro-grid, this presentation has fully analyzed the problem of using power electronics transformer in real applications. The methodology of handling these problems is also illustrated. Finally, the outlook of power electronics transformer in smart grid is presented.
