Design and Simulation of a 3 Phase 25 kV 20 kW 5 Hz Pulsed High Voltage Generator for Microorganisms Inactivation Process in a Liquid Food
Main Article Content
Abstract
A 3 phase 25 kV 20 kW 5 Hz pulsed high voltage generator for a liquid food microorganisms inactivation process was designed and described in this paper The designed generator consisted of a 3 Phase 20 kVA 22kV high voltage transformer, a high voltage capacitor of 1 μF, a spark gap, and bridge rectifier circuit. In this study, the designed circuit was computationally calculated by the Simulink/ MATLAB. It was found from the calculation results of the designed circuit that the peak pulsed high voltage (Vpeak) was about 35.5 kV with the pulse width of about 6 μs at repetitive pulses between 1, 3 and 5 Hz. The results in this study can be used to test inactivating microorganism efficiency of the liquid foods and further developing PEF system for food industry level.
