A Low Cost High Voltage Power Supply to Use in Electrospinning Machines

摘要

Nowadays. Researching in the electrospinning field has expanded significantly because electrospinning can create nanofiber scaffolds for the flourish of tissue engineering. The scaffold is essential a platform that supports the migration, proliferation of cells and formation of tissues for wound healing applications. Therefore, the developing of electrospinning is also mandatory for spreading of tissue engineering field at Vietnam. In electrospinning machines, the main components include a high voltage DC source, a syringe pump and a grounded collector. In this study, we designed a low-cost high voltage power for electrospinning process by using a Zero Cross Voltage Switching (ZVS) driver circuit and a flyback transformer. As a result, the power worked effectively and stably as well as we expected. To prove its advantage quality, we do an experiment and investigation to examining the high voltage in an electrospinning system; we found out a set of parameters in our conditions that give a good membrane of structure morphology at 15% (w/v) PCL, 1 ml/h, 17 KVDC, and 20 cm in distance between needle iip and collector.
