| Summary: | 碩士 === 長庚大學 === 電機工程學研究所 === 97 === This paper proposes a high voltage pulse electric field generator for liquid food Sterilization. The proposed circuit structure adopts full-bridge converter to generate a high DC voltage. While, the LLC resonant circuit is used to recover the energy trapped in leakage inductance of transformer with a high turns ratio and to achieve zero-voltage switching at turn-on transition of switches for increasing conversion efficiency. Finally, a prototype of high pulse voltage generator under output voltage of ±10 kV and maximum output power of 1 kW has been implemented to prove the feasibility of the proposed high voltage pulse electric field generator.
