“…A laboratory system typically processes liters per hour (or less), and a pilot plant typically operates at ten to hundreds of liters per hour, while commercial systems, however, must be capable of processing thousands to tens of thousands of liters per hour (Kempkes et al, 2008). As shown in Table 2, Ohio State University (OSU) has designed three series of PEF units that differ primarily in their fluid-handling capacity.…”

“…23, this design provided an optimal balance between the flow and field requirements, capable of maintaining consistent field strengths, the gap over which the field is applied must be proportional to the pipe diameter. This design is best utilized at 5 cm pipe diameters and below, which translates to 200 kV pulses (at 40 kV/cm) (Kempkes et al, 2008).…”

Water treatment is one of the most important issues for all walks of life around the world. Different from the conventional water treatment technology, the advanced power electronic pulse technology has unique features and advantages for the modern water treatment. Unfortunately, there is no literature reported to describe them in a comprehensive and systematic way. To fill this gap, an overview of modern power electronic pulse generators (PPGs) for water treatment is presented. This paper, for the first time, classifies the different types of PPGs from the viewpoint of pulse formation. Each of them is discussed, and the advantages and disadvantages are compared and summarized. Aside from that, this paper presents the development and trend of the pulse generators suitable for the specified water treatment processes such as electrolysis, sterilization, and discharge degradation. Finally, a list of more than 100 relevant technical papers is also appended for a quick reference.

“…PEF modulation has three main components [28], [29], The first is a DC power supply that transitions AC power from the utility to high voltage DC power; the second is a pulse modulator which converts this average power into short and high peak power pulses; and the third is the mechanism of the delivery device to the stirring rod, which functions as the PEF process is applied to food. PEF modulation as bipolar (voltage + and -pulses) or monopolar (all + or all -pulses).…”

Realized a high-voltage pulse generator (HVPG) in a pulsed electric field (PEF). The honey pasteurization process with a PEF uses short electrical pulses to honey nectar through electrodes directed at a stirring rod, which deactivates spores and fungi. The PEF is a non-thermal technology for honey preservation. PEF is applied for vessels with a capacity of 80 liters to support micro, small, and medium enterprises; they have yet to make it so far. This study aimed to produce an HVPG design in randu honey preservation by controlling treatment time and specific input energy requirements. The modulation uses pulse width modulation (PWM) on a 50% duty cycle microcontroller. The first pasteurization was through a heating process for 60 minutes, followed by testing the effectiveness of PEF by adjusting the suitability of the processing time for 60 minutes. Measurement of the treatment time after the pasteurization process shows that the average voltage and current used are 25kV~40kV and 0.3A. The electric field strength sent to the stir bar is 0.33kV/cm. During the pasteurization process of randu honey, the temperature setting is gradually increased to 70°C, with the heating process for 60 minutes, and the process stops. The honey process continues to apply PEF for the temperature decreases to 24°C in the honey liquid. This aims to deactivate the spores and herbs without causing loss of the sensory and physical properties of the honey liquid.
