Physical Design of a 300 kV Double Windings Pulse Transformer

Abstract

In order to develop a repetitive frequency accelerator, a repetitive pulse transformer with output voltage (U_2m) of 300kV, average power of 40kW, and more than 500ns pulse duration has been designed and tested. The primary and secondary windings are double coils, which consist of four shunt segments. Its characteristics consists in improving the electric field of windings uniformity. Using an amorphous alloy core helps to improve pulse waveform of output voltage and increase energy transfer efficiency. The experimental results show that the transformer can satisfy designed requirement.
