Çalışma, laboratuvar kullanımları için düşük maliyetli bir yüksek voltaj devresi geliştirmeyi ve sprey damlacıklarının elektrostatik yüklenmesinde performansını ticari bir devre ile karşılaştırmayı amaçlamaktadır. Cockcroft-Walton voltaj çarpanı en basit ve ucuz olarak kabul edildiğinden, bu devreyi tasarlamak için kullanılmıştır. Devrenin geliştirilmesinde iki adet d.c-a.c evirici (yüksek ve düşük frekanslar) ve iki kapasiteli kapasitörler kullanılmıştır. Kondansatör kapasitesinin ve voltaj frekansı değerinin devrenin çıkış voltajı, çıkış voltajı dalgalanması ve tepki süresi üzerindeki etkisini incelemek için devreye farklı elektrik akımı değerleri yüklenmiştir. Elde edilen sonuçlara göre, düşük frekanslı ac invertör ve düşük kapasiteli kondansatörler ile geliştirilen devrenin mikroamper dahil akımla yüklenmesi çıkış gerilimini ve gerilim dalgalanmasını ciddi şekilde etkilemiştir. Bununla birlikte, 20 kHz yüksek frekanslı invertör ve 470 nF kapasitörler, farklı yük akımlarında çıkış ve dalgalanma voltajını önemli ölçüde iyileştirmiştir. Ayrıca tepki süresini 15 saniyeden 40 milisaniyeye düşürmiştir. Geliştirilen yüksek gerilim devresi, su damlacıkları yüklemesinde ticari devre ile aynı verimi sağlayabilmektedir. Üstelik, geliştirilen bu devre 15 kV'a kadar yüksek voltaj değeri sağlayacak şekilde geliştirilmiştir.

The study aimed to develop a low-cost high voltage circuit for laboratory uses and compare its performance with a commercial one in the electrostatic charging of spray droplets. Because the Cockcroft-Walton voltage multiplier is considered the simplest and cheapest, it was used to design this circuit. Two d.c-a.c inverters (high and low frequencies) and capacitors with two capacities were used in the development of the circuit. The circuit was loaded with different electric current values to study the effect of the capacitor capacity and frequency value on the circuit's output voltage, output voltage ripple, and response time. According to the results, loading the circuit developed with a low-frequency inverter and low-capacity capacitors by current, even including the microampere, seriously affected the output voltage and the voltage ripple. However, a 20 kHz high-frequency inverter and 470 nF capacitors significantly improve output and ripple voltage at different load currents. Also, they reduced the response time from 15 sec to 40 msec. The developed high-voltage circuit can provide the same efficiency in water droplet charging compared with the commercial one. Moreover, this developed circuit was enhanced to provide a high voltage value until 15 kV.
