HT-6M托卡马克加热场脉冲电源的设计

Design of Pulse Power Supply for HT-6M Tokamak Heating Field

HT-6M托卡马克装置重建是为响应“一带一路”倡议的中泰合作国际项目,加热场脉冲电源的作用是击穿和产生等离子体,其电源方案采用电容储能脉冲放电形式。为计算出满足要求的电源参数,对加热场脉冲电源放电过程进行数学分析,并根据电源设备的工作参数,设计并研制了电源的核心器件。为验证电源放电过程的理论分析,研制了一套小型电容储能脉冲电源,证明理论分析正确性的同时,对电源大功率固态断路器进行关断实验。

The HT-6M Tokamak Reconstruction is an international project of cooperation between China and Thailand for responding to the Belt and Road Initiative.The function of pulse power supply for heating field is to breakdown and produce plasma,and the corresponding power supply scheme adopts the form of capacitor energy storage pulse discharge.To calculate the parameters of power supply that meet the requirements,the discharging process of pulse power supply for heating field is analyzed mathematically,and the core devices are designed and developed according to working parameters of power supply equipment.To verify the theoretical analysis of discharging process,a set of small capacitor energy storage pulse power supply was developed.At the same time,a turn-off experiment on a high-power solid-state circuit breaker was carried out.
