“…The high-voltage pulse source designed by Ruchiharchandani et al has a maximum output voltage of 92 V in a two-stage circuit with an input voltage of 50 V [23], and the device's pulse rising edge is greater than 500 ns. The four-stage circuit designed by Dwarakanath et All the Marx generators designed in the literature [28][29][30][31][32][33][34][35] are isolated with resistors or diodes, and none of them have a dual-Marx structure. The 10-stage circuit developed in the experiments in this paper can simultaneously output two output voltages with a positive input of 100 V and a negative input of −100 V. The output voltage of the 10-stage circuit can be reduced to 1 V with an input of 100 V and a negative input of −100 V. The output voltage of the 10-stage circuit can be increased to 2 V at the same time.…”

To meet the application requirements of pulsed power technology in wastewater treatment and other aspects (for example, a scenario that requires a high-voltage pulse source that can output a pulse with a rising edge in the nanosecond range and a device that can stabilize the pulse under high-frequency conditions), this paper designed an inductively isolated bipolar high-voltage pulse source. It consists of three parts: the primary charging power supply, the isolated driver circuit, and the pulse-forming circuit. By using inductance instead of traditional resistance isolation, using the inductance for charging and isolation, the inductance can increase the charging voltage of the capacitor, so the circuit can achieve a higher voltage output. The dual-Marx generator parallel connection design of the pulsed power supply topology, using a primary charging power supply for positive and negative polarity charging, can simultaneously output the reverse polarity and size of high-voltage pulses to achieve a bipolar output, so the load has an effect on the pulse. The equipment was selected on the basis of the design of the isolated driver circuit, primary charging power supply circuit, and pulse-forming circuit for the corresponding simulation, and in the experiment to build a principle model, the tests showed that the pulse source output pulse amplitude range was 0~10 kV (the positive pulse voltage was 5 kV, and the negative pulse voltage was −5 kV), the pulse rising edge was approximately 200 ns, the pulse width was 1 μs, and the frequency range was 0~1 kHz for the pulse source frequency. The power supply was designed to be used in applications such as wastewater treatment.

“…Therefore, controlling turn-on speeds of switches can adjust both the rise and fall time of pulses. Since the principle of SSMG have been studied in many papers [27][28][29][30], this paper focuses on the drive circuit and its principle.…”

A high‐voltage solid‐state Marx generator with adjustable pulse edges

Most reactors for non‐thermal plasma excitation are capacitive to pulse generators. The density and temperature of electrons in plasma are dominated by the discharging currents which are proportional to the pulse edges. However, adjusting the pulse edges is quite challenging since the switching speed and the inductance and capacitance in the discharging loops dominate them. This study proposes a drive circuit for solid‐state Marx generators with adjustable edges. The drive circuit controls the Miller plateau by adjusting the gate voltage amplitude to adjust both the rise time and fall time of pulses continuously and independently. The influence of the gate voltage on the Miller plateau and the rise time is studied. The feasibility is verified by both simulating and experimental results. An 8‐stage solid‐state Marx generator prototype was built, and 4.8‐kV pulses with a rise time in the range of 79 ns‐22.21 μs were obtained over capacitive loads. Adjusting pulse edges can control the current amplitudes in dielectric barrier discharge loads.
