![]() ![]() The output voltage of converter was relatively stable and good enough to perform nanofibers synthesis using the needleless electrospinning. The single converter could generate a high voltage up to 34kV whereas the series-configuration converter could increase the voltage by 98.41% to be 67kV. The output voltage was adjusted by changing the input voltage. ![]() ![]() Two converters were connected in series to achieve more output voltage. The Mazzilli flyback converter was able to generate a high voltage with relatively high power. ![]() Accordingly, the high voltage power supply using a series-configuration Mazzilli ZVS flyback converter was designed and developed. Therefore, the high-voltage source required for the needleless electrospinning process must have a higher voltage and current compared to those for the needle one. The latter is intended for mass production nanofibers because it can make tens to hundreds ofjets at a time. There are two types of electrospinning method they are needle and needleless electrospinning. Usingthe high electric field, the charged polymer solution is formed as a Taylor cone and then drawn to the collector to form long, nanoscale fibers. It can be formed by applying a high-voltage source to a polymer solution so that the polymer solution becomes charged. Nanofiber is one-dimensional material that has broad application. ![]()
