Development of a Compact Repetitive High-voltage Pulse Transformer

By combining pulse transformer and pulse forming line(PFL),a kind of compact pulse transformer is built and its configuration is more compact.The basic theory and method of the compact pulse transformer are briefly introduced,and some key technologies are put forward in design.Then the charge voltage waveform of PFL and the load voltage is simulated by Pspice.The simulated results show that the pulse transformer can charge PFL up to 1.7 MV.Based on the theory,a compact repetitive high-voltage pulse transformer is developed by IAE,CAEP.The results of testing show that the compact pulse transformer can charge PFL to 1.75 MV at single pulse,and keep on an average voltage of 1.65 MV at 100 Hz.
