Abstract

In this paper, a novel new pulse power generator based on IGBT stacks is proposed for pulse power application. The proposed scheme consists of series connected 9 power stages to generate maximum 60 kV output pulse and one series resonant power inverter to charge DC capacitor voltage. Each power stage is configured as 8 series connected power cells and each power cell generates up to 850 V DC pulse. Finally pulse output voltage is applied using a total of 72 series connected IGBTs. The synchronization of gating signal is important for series operation of IGBTs. For gating signal synchronization, a full bridge inverter and a pulse transformer generates on-off signals of IGBT gating and specially designed gate power circuit was used. The proposed scheme has lots of advantages such as long lifecyle, compact size, flat topped pulse forming, small weight, protection for arc, high efficiency, and flexibility to generate various kinds of pulse output. The operation of proposed pulse power supply was tested for PSII application and is confirmed that the proposed scheme can effectively be used for wide pulse power applications

应用广泛的基于IGBT堆的60kV脉冲发电机的研制

本文提出了一种新型的基于IGBT堆叠的脉冲功率发生器。该方案由串联连接的9级功率产生最大60kv输出脉冲和一个串联谐振功率逆变器对直流电容电压充电组成。每个电源级配置为8个串联连接的动力电池，每个动力电池产生高达850 V的直流脉冲。最后脉冲输出电压是使用总共72串联连接的igbt施加的。门控信号的同步对igbt的串联工作至关重要。门控信号同步采用全桥逆变器和脉冲变压器产生IGBT门控通断信号，采用专门设计的门控电源电路。该方案具有寿命长、体积小、平顶脉冲成形、重量小、电弧保护、效率高、可灵活产生各种脉冲输出等优点。在PSII应用中对所提出的脉冲电源进行了运行测试，证实了所提出的方案可以有效地用于宽脉冲功率应用
