The momentum of pulsed electric field (PEF) in maintaining food quality has increased due to its ability to treat food without the use of thermal elements. To achieve this, high pulse voltage must be used in conjunction with the pulse signal controller. Therefore, this paper presents the development of advanced pulse signal controllers using Arduino Uno. It can produce an adjustable pulse width from 63 ns (min) to 4 ms (max) along with an adjustable gap between pulses from 1 µs (min) to 10 s (max). A laboratory experiment was performed on a NaCl solution to record its performance in producing the desired pulse attribute. The results show that the pulse signal controller successfully delivers the intended pulse. A clean 4.25 A square pulse electric current was recorded in the absence of abnormal effects. This proves that the proposed method works as expected and also proves the concept presented. Practical applications The practical application of this research is more to the development of advanced electroporators that can meet current demand. It can produce pulses as low as 63 ns to 4 ms (maximum). By using the microcontroller available in the local market, it can reduce development costs while providing a reliable pulse. In addition, the pulse generated is also TTL and CMOS compatible and makes it useful for driving any digital switching device such as MOSFET and IGBT. Extensive applications are not limited to PEF, but also other pulse applications. Therefore, this study is very worthwhile to be implemented and commercialized besides being able to produce PEF treatment technology that is cheap, reliable, and robust.

“…Voltage pulses are created by a transistor switch, which connects the capacitor directly to the load for a certain time. MOSFET transistors are usually used up to 1 kV voltage level, for higher values, IGBT transistors are suitable [19]. The capacitor bank is usually charged from the rectified AC mains by voltage regulator, which allows to set the output voltage.…”

This paper is focused on a design of a high-voltage (HV) generator, which is proposed for a high-frequency irreversible electroporation (H-FIRE). The generator produces bursts of bipolar symmetrical pulses. Most HV sources used for cell electroporation are based on a controlled discharge of a capacitor into a resistive load. This solution is very simple, but it is associated with a certain risk of an uncontrolled discharge of the capacitor. We present a different type of the generator, where a DC-AC inverter with pulse transformer is used and where the mentioned risk is eliminated. Our generator is able to deliver bursts with variable length from 50 to 150 μs and a gap between bursts can be set from 0.5 to 1.5 s. Pulse frequency can be varied from 65 to 470 kHz and the output voltage is controlled in two ranges from 0 to 1.3 kV or from 0 to 2.5 kV. Results are presented with resistive load and with tissue impedance load.

“…But, the classical switches have the drawbacks such as: the repetition rate is limited (less than 100 Hz), the complex triggering circuit design and the switching time delays which try to alter the wave-shape. But, the embellished technological improvements in semiconductor technology have been brought in PEF systems to make them efficient [18,[22][23][24][25][26]. This paper proposes a high-voltage pulse generator that focuses on reducing the input DC voltage requirement for the high-voltage pulse generation by selecting cascaded boost converter topology as a front-end converter.…”

Food processing technologies for food preservation have been in constant development over a few decades in order to meet current consumer's demands. Healthy competitive improvements are observed in both thermal and non-thermal food processing technology since past two decades due to technical revolution. Among these novel technologies, pulsed electric field food processing technology has shown to be a potential non-thermal treatment capable of preserving liquid foods. The high-voltage pulse generators specifically find their applications in pulsed electric field technology. So, this paper proposes a new structure of a high-voltage pulse generator with a cascaded boost converter topology. The choice of a cascaded boost converter helps in selecting low DC input voltage and hence the size and space requirement of the high-voltage pulse generator is minimized. The proposed circuit is capable of producing high-voltage pulses with flexibility of an adjusting duty ratio and frequency. The designed circuit generates a maximum peak voltage of 1 kV in the frequency range of 7.5-20 kHz and the pulse width range of 0.8-1.8 µs. Also, the impedance matching between the cascaded boost converter and the high-voltage pulse generator is found simple without further additional components. The efficiency can be improved in the circuit by avoiding low frequency transformers.
