Design and Construction of A Non-Thermal System Based on High Pulsed Electric Fields Using Flyback TV

Abstract

Food safety is a critical issue that requires innovative technology to reduce pathogenic microorganisms without compromising nutritional quality. Therefore, this study aims to design and test a High Pulsed Electric Field (HPEF) system using a TV flyback transformer as a high-voltage source. The study also aims to determine the output voltage and the effectiveness of the device in generating an electric field for non-thermal processes. The HPEF device was designed using key components such as a TV flyback transformer, transistor, relay, capacitor, and a 12V adapter. The observed parameters included structural and functional analysis of the device, covering dimensions, input power, working processes, and output voltage. Output voltage measurements were conducted using a digital multimeter and a voltage divider resistor to ensure safe and accurate readings. The results showed that the designed device was capable of generating an average output voltage of 3,133.64 VDC. The device dimensions were 30 cm in length, 20 cm in width, and 10 cm in height, with optimal performance achieved based on the configured circuit design. The high voltage generated was stable and sufficient to create the electric field needed for non-thermal processes. In conclusion, the HPEF device designed using a TV flyback transformer successfully generated stable high voltage at an economical cost. This technology provides an effective alternative solution for non-thermal pasteurization, preserving nutritional quality while enhancing food safety.
