Outline of Final Research Achievements

Pulsed power is electrical energy released in short time. It is characterized by instantaneous high power. For this reason, it has unique applications in the fields of energy, material, environment, light source, and etc.
This research aimed at the development of repetitive pulsed power generators for industrial applications. By adapting a new technical approach called LTD, it is proved to be significantly different from traditional methods in compactness, stability and modularity.　In the demonstration experiments, 30 LTD modules have been connected together in series to form a pulsed high-voltage generator, which is capable of generating pulsed output voltage of ~30 kV. In addition, FPGA has been used to control the output of the LTD to prove the flexibility of the output waveform.
