摘　　要：为提高电功率密度、减小能量损失,对于电容放电加载的半导体桥,提出缩短桥长是降低发火能量的有效途径的观点。利用半导体桥阻抗温升特性的不可逆现象,提出通过加热预处理减小初始电阻,从而降低半导体桥发火能量的方法。Based on theory of decreasing energy loss by increasing electric power density, shortening bridge length is advised as an efficient way to decrease firing energy of semiconductor bridge, which is fired by capacitance discharge. Based on unreversibility of resistance change with temperature, decreasing initial resistance by heat pretreating semiconductor bridge is also an efficient way of decreasing firing energy.
