N2 - Pulsed electric field (PEF) technology is a promising non-thermal pasteurizati on method that can be utilized to inactivate microorganisms in liquid food with high-voltage PEF. The power switch which is an important component of the PEF systems. This paper presents a design and implementation of an insulated gate bipolar transistor (IGBT) module which includes connections of three series and four parallel IGBTs and its special gate driver for small liquid food treatment systems at home. In this approach, two important issues must be considered. The first is to provide a safe operating condition for each single IGBTs in transient intervals. The second is to design gate drive systems with the capability of driving a large number of discrete devices simultaneously and ensure the current and voltage of single IGBTs in the module to be approximations. To evaluate the operation of the proposed structure, a module of three series and four parallel switches with the voltage capability of 1.8 kV and 60A is tested experimentally.
