摘要

高压脉冲电场(PEF)在非热食品加工中的应用越来越广泛。本文介绍了一种基于IGBT的12kv固体高压脉冲发生器的设计。该脉冲发生器采用了简单的主电路拓扑结构，既降低了成本，又满足了PEF食品加工的要求。智能IGBT模块，额定电压为1200v和1200a，在逆变电路中作为电源开关。为解决设备高度集成化带来的电磁干扰，设计了复杂的接地系统。为了塑造输出脉冲电压波，设计了专用的直流母线，以减小电流回路中的杂散电感。本文给出了实验结果。

A 12 kV solid state high voltage pulse generator for a bench top PEF machine

High voltage pulsed electric field (PEF) is increasingly used for nonthermal food processes. This paper presents a design of an IGBT based 12 kV solid state high voltage pulse generator. A simple main circuit topology is employed in this pulse generator to reduce the cost and meanwhile still to meet specified requirements for PEF food processing. Intelligent IGBT modules, rated 1200 V and 1200 A, are used as power switches in the inverter circuit. A sophisticated grounding system is implemented to solve EMI caused by high integration of the equipment. In order to shape output pulse voltage wave, a dedicated DC bus for the inverter is developed to minimize stray inductance in the current loops. Experimental results are shown in this paper.
