Physical design and simulation of LTD-based source with long pulse and high power

A linear transformer driver (LTD) module with 150 kV output capability was designed based on a former 125 kV LTD module, which used Blumlein line as the pulse forming line. A 600 kV LTD system was contrived with four newly designed modules connected in series. Calculation and simulation were done, respectively, to decide the dimensions of the secondary coil of the LTD equipment which also sufficed the requirement about insulation, and to analyze the influence of input mode on output pulse. The results show that the output pulse waveform of the left input type is better than the right input type, and compared with the unilateral input mode, the rising time of the symmetrical input mode is shorter. The result of circuit simulation proves that the LTD system can drive a 40 Ω load with a 600
