Integrated high voltage generator with ATmega 328 microcontroller using flyback transformer

Abstract

The method of increasing the output voltage at high voltage generator using two Fly-back Transformers (FBT) arranged in a series circuit integrated with AT-MEGA328 has been successfully created and tested. This method is done by doubling the output voltage by arranging two FBT in a series electrical circuit. Additionally, the ATMEGA328 microcontroller is integrated into this system to regulate the frequency and duty cycle in ideal conditions in the process so that the output voltage becomes more optimum. The test results show that this method has succeeded in increasing the output voltage by 93.91% by adjusting the frequency and duty cycle of this process at the values of 3000Hz and 60% respectively. The success of this research is very useful to be applied in various fields that require high voltage such as milk pasteurization system, dielectric for food, food sterilization, air purifier, and other applications.
