【 摘 要 】

The elongated plasma has vertical displacement instability, which could be retrained by active control. The topology of the second-generation fast control power supply is three-phase uncontrolled rectification and H-bridge inverter structure, which can achieve fast response (less than 1 ms) and large rated current (6 kA). But the power supply requires to further improve the power quality and achieve the recuperation of braking energy. The main topology is optimized. This paper will introduce the optimized fast control power supply that adopted three-phase voltage source PWM rectifier. The simulation and experiment results show the correctness of the theoretical analysis and provide the technical reference for the vertical stability fast power supply in other Tokamak devices.
