| 摘 要： | 对晶闸管在高功率脉冲电源中的应用进行了探讨;指出通态不重复浪涌电流、通态电流临界上升率是晶闸管选取的实际依据;给出了脉冲电流上升率的计算公式,确定了晶闸管通态电流临界上升率的最低取值。采用缓冲电路对晶闸管进行保护,通过理论分析得出了阻容匹配条件。仿真和实验表明该电路能有效抑制时序工作方式下出现的浪涌电压;将晶闸管作为主电路开关应用于一台由8个模块组成的高功率脉冲电源时,可取得良好的效果。

| Abstract: | The application of the thyristors in pulsed power supply is discussed.It indicates that the pratical selection of thyristors is according to the non-repetitive peak on-state current and the critical rate of decrease of commutating on-state current,and gives the formula of increase rate of pulsed current,which obtains the minimum value of the critical rate of decrease of commutating on-state current.The thyristors are protected by the snubber circuit,and the value of snubber resistence and snubber capacitanc... |
