High voltage pulse power implementation using IGBT stacks

摘要

High voltage pulse power implementation using IGBT stacks is proposed in this paper. High voltage pulse power implementation uses Marx circuit as the main circuit. The Marx circuit is composed of 12 stages and each stage is made of IGBT stack, two diode stacks, and capacitor. Diode stacks and inductor are used to charge high voltage capacitor of each stage without power loss. These are also used to isolate input and high voltage negative output in high voltage generation mode. The proposed pulse power generator uses IGBT stack with a simple driver and has modular design. So this system structure gives compactness and easiness to implement total system. Some experimental and simulated results are included to verify the system performances in this paper.
