Abstract

This paper presents a method for generating a high voltage between 3 – 27 kV from a commercial flyback transformer. It’s useful in high voltage fields such as ionization or plasma applications. This high voltage generation method has consisted of an open-loop control that depends on the electric load and closed-loop control for setting a discharge current constantly. The high voltage is generated from the conventional switch circuit and use a PWM control signal from NE555 and TL494 controller. In addition, it had a gate drive circuit from the TLP250 controller. The LM741 is used for converting and amplify a discharge current to voltage signal for closed-loop control by UC3842 controller. The results show that every method can generate a high voltage and show the nonlinear characteristic between high voltage output and frequency changes. The electrical power of the commercial flyback transformer has about 20 W.
