A high-voltage transmission-line pulse transformer with very low droop

The design, construction, and operational characteristics of a 200 kV transmission line pulse transformer is described. The transformer is wound using a new winding method that enhances the isolation of the output of the transformer from the input. As a result, pulse droop is substantially reduced, minimizing pulse distortion in the transformer. The ways in which both pulse rise time and droop can be further improved are investigated using a simple model for the transformer. The frequency response performance of the transformer is also described and modeled. As a result, it is shown that this type of transformer has the potential to be used as a high-frequency, continuously excited power transformer.
