“…The capacitances were selected equal to 230 µF resulting from (10) in a voltage drop of about 35 V. Since the maximum current allowed by the primary dc voltage source was 0.5 A and each period is 100 ms, the simulations indicated that inductors with L = 320 mH were a suitable choice. This value is also in between the bounds given in (15) and (16), which yield that L 1 should be between 705 mH and 171 mH, respectively. As Fig.…”

“…Some of the topologies previously suggested using semiconductor devices can produce bipolar pulses, but they require one more capacitor, one more controlled switch, and one more diode in total than the circuit proposed here, regardless of the number of circuit stages [13], [14]. Other configurations are only able to produce unipolar pulses unless the ground and load connections are changed offline [15]- [20] and they tend to have more switches. Namely, the configurations in [15]- [20] require at least 1.5 times more switches than the Marx stage of the proposed topology here for the same unipolar output voltage, as it will be described in Section II.…”

“…Since the topologies in [15]- [20] can only achieve unipolar pulses, they are compared with the Marx stage only in the bipolar circuit discussed here. In the case of [15]- [18], they require 1.5 times more switches than the Marx stage of the circuit proposed here, whereas the configurations in [19] and [20] require 3n + 3 (2n + 1 controlled switches and n + 2 diodes) and 4n + 2 semiconductor switches (2n + 2 controlled switches and 2n diodes), respectively, versus 2n (n controlled switches and n diodes) in the Marx stage of the circuit in Fig. 4.…”

Namely, the configurations in [15]- [20] require at least 1.5 times more switches than the Marx stage of the proposed topology here for the same unipolar output voltage, as it will be described in Section II. In contrast and as it is discussed in Section II, the proposed topology here is not only capable of generating bipolar pulses without offline reconfigurations, but it also requires fewer switches even when the output is increased to levels higher to those found in commercially available insulated gate bipolar transistor (IGBTs), hence, leading to a more cost effective solution.…”

This paper presents a high-voltage bipolar rectangular pulse generator using a solid-state boosting front-end and an H-bridge output stage. The topology generates rectangular pulses with fast enough rise time and allows easy step-up input voltage. In addition, the circuit is able to adjust positive or negative pulsewidth, dead time between two pulses, and operating frequency. The topology can also be controlled to produce unipolar pulses and other pulse patterns without changing its configuration. With an appropriate dc source, the output voltage can also be adjusted to requirements of different applications. The intended application for such a circuit is algal cell membrane rupture for oil extraction, although additional applications, include biotechnology and plasma sciences, medicine, and food industry. A 1 kV/200 A bipolar solid-state pulse generator was fabricated to validate the theoretical analysis presented in this paper. In addition, to validate the analysis with simulations and prototype tests, biological test were conducted in order to examine the technical value of the proposed circuit. These evaluations seem to suggest that oil production rate from bipolar pulses may double that of an equivalent process with unipolar pulses.

Abstract:The purpose of this paper is to present and discuss a general HV topology of the solid-state Marx modulator, for unipolar or bipolar generation connected with a step-up transformer to increase the output voltage applied to a resistive load. Due to the use of an output transformer, discussion about the reset of the transformer is made to guarantee zero average voltage applied to the primary. It is also discussed the transformer magnetizing energy recovering back to the energy storage capacitors. Simulation results for a circuit that generates 100 kV pulses using 1000 V semiconductors are presented and discussed regarding the voltage and current stress on the semiconductors and result obtained.

Day by day, the need for renewable fuel has increased to reduce the usage of non-renewable fuels and also to provide adequate fuel for vehicle use worldwide. Organic fuels that can be derived from different sources are renewable fuels, of which oil extracted from algae cells can also be used as a biofuel. Algae oil extraction can be achieved by applying a Pulsed Electric Field across the algae cell to rupture its membrane and to remove oil. A Pulse Generator, capable of carrying out this operation, although in existence, has some drawbacks including lack of versatility, performance and reliability, etc. Pulse generators can also be used for many other purposes, including cancer cell ablation, water treatment, thunder and lightning safety testing of electrical equipment, lasers, radar systems, military, etc. Hence a Pulse generator capable of generating the necessary Pulse patterns, maintaining a reasonable efficiency and performance, including features such as versatility, simple input voltage stepping, high switching frequency etc. The design of a novel solid-state-based topology with the required features is considered to be the main objective of this work. In this paper, we aim to present the design and simulation of the proposed circuit, along with some results obtained.
