摘要
利用快速高重复频率的脉冲凸轨技术可以实现合肥光源的光脉冲间隔的可调。为了获得这一快速高重复频率的强流短脉冲,采取基于MOSFET的固态调制器技术。设计出了一套10路MOSFET开关并联、6级感应叠加的实验样机结构,包括快速时钟信号产生、功率驱动电路设计、感应叠加式阵列结构。样机获得了底宽为100 ns、重复频率20 kHz、峰值电流60 A、峰值电压2 kV的功率脉冲。
Pulse bump orbit technique can realize adjustable interval of Hefei light source HLS light pulse. In order to obtain high-current short pulse with high repeat frequency for the fast kicker, the experimental study based on the MOSFET solid modulator technique was carried out. The designed prototype has the structure of a 10-group MOSFET switch parallel and a 6 level in- ductive-adder, including fast trigger signal production, power drive circuit＇s design, inductive-adder type configuration. The device obtains a pulse output of 100 ns width, 20 kHz repeat rate, 60 A summit current and 2 kV peak voltage.
