A novel interleaved structure high-voltage transformer and its application in TWTA

This paper proposes a planar high voltage interleaved transformer design method. The transformer is suitable to be used in power supply for TWT. Since the parasitic parameters of the transformer are adopted as resonant elements, the cross regulation problem is alleviated. Moreover, the iteration of FEA simulation and circuits design will greatly reduce the cost of design. The method is verified by a 600W multiple output power supply for TWTA, and the performance of the prototype shows this method is effective.
