Design and Implementation of Pulse Electric-Field Generator for Liquid Egg Sterilization Applications

The objective of the project to design and implementation of pulse electric-field generator (PEFG) for liquid egg sterilization applications. In this research, the proposed PEFG, which adopts a bidirection flyback converter with the energy recovery manner, and micro controller, can generate maximum output voltage of 30kV, maximum output power of 50MW, maximum pulse width of 500ns and the repetition of 5 times within one second interval. Moreover, the project will implement a dynamic sterilization chamber for liquid egg application and establish a technical platform for further liquid food sterilization research and conduct system commercialization except that high PEFG designs. In this research, the designed systems are highly innovative and feasible. They are relatively competitive to use switching power processing technology because they possess small volume and facilitate to implement module and to maintain them. Our research group has already accumulated the design experience of high voltage generator for many years. In addition, we have implemented the proposed system for juice and water sterilizations. Therefore, we strongly believe that we are able to fulfill the goals of this project. We hope not only to incubate the cross-field researcher, but to increase the competitiveness of industry.
