Abstract |
200kV pulse power supply implementation based on IGBT stacks is implemented in this study. The pulse power supply uses Marx circuit as high voltage pulse generator. The Marx circuit is composed of 20 stages and each stage is made of IGBT stack, two diode stacks, and capacitor. It can generate the pulse voltage with the following parameters: Voltage: up to 200kV, Rising time: sub μS, Pulse width: up to 4μS, PRR: 1000pps Inductive and diode charging method is used to charge high voltage capacitor of each stage without power loss. The proposed pulsed 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. |
