“…When C 1 is 41.6μF, the corresponding curve has larger (i 1 ) max than another one. Equation (8) indicates that C 1 has no effect on (di 1 /dt) max . However (di 1 /dt) max for two values of C 1 still has a tiny deviation.…”

“…The circuit resistance, the turn-on resistance of thyristor and other factors are not considered when equation (8) is deduced. When i 1 changes, these ignored factors may have some effects on the calculation result of equation (8). Secondly, k eff is supposed to be unchanged as the prototype is constructed.…”

Air-core Tesla transformer combined with semiconductor devices can generate repetitive high-voltage pulses effectively. Air-core Tesla transformer of spiral type is suitable for repetitive operation since its primary voltage is relatively low. Based on the double resonance circuit of air-core Tesla transformer, the expressions of secondary voltage, primary current, and the maximum rise-rate of primary current are deduced. The effects of tuning characteristic on the output voltage and energy efficiency are simulated, and further verified by experiments. An air-core Tesla transformer prototype of spiral type is developed. To achieve repetitive operation, a resonant charging and discharging circuit based on air-core Tesla transformer is designed. The repetitive system based on this prototype can generate microsecond pulses with an average peak voltage of -140 kV at 300 Hz repetition rate. In repetitive mode, the tuning ratio is recommended to range in 1.0-2.0 to achieve high energy efficiency. The output voltage could be higher by increasing the charging voltage or tuning ratio.

“…One is the Tesla transformer, for example, the Sinus-type ultra-wideband system developed by the Institute of High Current Electronics (HCEI) [9][10][11][12], and RADAN series developed at the Institute of Electrophysics [13]. e other is to use the Marx generator to generate high-voltage pulse for driving bipolar pulse [14][15][16][17]. According to the published literature, the volume and weight of 10 GW bipolar pulse generators are relatively large, which limits the further application of the system.…”

A compact high-power ultra-wideband bipolar pulse generator based on a modified Marx circuit is designed, which is mainly composed of a primary power supply, Marx generator, sharpening and cutoff subnanosecond spark gap switches, and coaxial transmission lines. The Marx generator with modified circuit structure has thirty-two stages and is composed of eight disk-like modules. Each module consists of four capacitors, two spark gap switches, four charging inductors, and a mechanical support. To simplify the design of the charging structure and reduce the number of switches, four groups of inductors are used to charge the capacitors of the Marx generator, two of which are used for positive voltage charging and the other two for negative voltage charging. When the capacitor of each stage is charged to 35 kV, the maximum output peak voltage can reach 1 MV when the Marx generator is open circuit. The high-voltage pulse generated by the Marx generator charges the transmission line and forms a bipolar pulse through sharpening and cutoff switches. All transmission lines used for bipolar pulse generation have an impedance of 10 Ω. When the 950 kV pulse voltage generated by the Marx generator is fed into the transmission line, the bipolar pulse peak voltage can reach 390 kV, the center frequency of the pulse is about 400 MHz, and the output peak power is about 15.2 GW.

“…In the last few years, high-intensity pulsed fields are getting increasingly more attention and find new applications in different domains such as biology, 1,2 industrial processes, 3 physics, 4 and military. 5 Some of them do not necessarily need high power or very high voltages-sometimes less than 10 kV can be sufficient. On the other hand, they need more controllability, flexibility, compactness, and long lifetime, which is not the case for traditional pulse generators such as Marx.…”

In order to test the electroporation applied to mammalian cells (DU-145 human prostate cancer cell line), treated with short (30 ns) intense electric pulses, a new architecture of a pulse generator is proposed. It provides a quasirectangular output with nanosecond rise time and fully controlled repetition rate, which allows the control of the electric field dose applied to the cells.The system consists of a pulse generator with a high voltage gain and power efficiency, but it outputs exponential pulses. To improve that side, a pulse forming line (PFL) is used to get the final rectangular pulse. The whole device is designed using a multilayer printed circuit board (PCB) technology. That reduces the cost and increases the compactness of the generator. The output is connected to a special electroporation cuvette filled with special liquid. The impedance of such load is not well known, that is why some preliminary tests were carried out to identify the load of the generator. A number of simulations allowed to validate the design and to find out the influence of different parameters on its characteristics. Finally, a compact 4-kV generator was built and tested. The results are discussed and compared with those obtained from simulations.
