摘要
将ICCOS换流原理应用于STRETCH meat grinder电路中的电感储能型脉冲电源新型拓扑具有有效提高关断电流和降低系统成本的优势。为构建电气性能和非电性能最优的电感储能型脉冲电源系统,对基于ICCOS的STRETCH meat grinder电路的逆流回路的分析和优化设计是必要的。基于ICCOS的STRETCH meat grinder电路的理论分析,结合初步实验结果,本文提出了ICCOS逆流回路的基本设计约束,通过逆流电容值及其预充电压的优化取值,使逆流能量最小。仿真分析表明,ICCOS最小逆流能量和所要关断的电流大小直接相关,且受到一次直流电源的影响,而与所关断的电感初始储能大小无关。
By applying the principle of inverse current commutation with semiconductor devices （ICCOS） in a slow transfer of energy through capacitive hybrid （STRETCH） meat grinder circuit, a novel circuit topology of inductive pulsed-power supplies can not only raise the amplitude of opening current, but also can reduce the cost for STRETCH meat grinder obviously. In order to construct high energy inductive pulsed-power supplies with the best performance, the parameter analysis and optimization design are necessary for its ICCOS countercurrent circuit. Combined with the initial experiment result, this paper put forward design constraints of the countercurrent circuit based on the analysis of the principle of STRETCH meat grinder with ICCOS. It shows that there is a group of optimal values for countercurrent capacitor and its precharge voltage with the minimum of countercurrent energy. Simulation analysis showed that the minimum of countercurrent energy is directly related to the corresponding opening current and get the influence of the primary dc power supply, but has nothing to do with the inductor energy.
