摘要
动态电路换路时 ,若存在由纯电容和理想电压源构成的回路 ,则电容电压就有可能跃变 ,在含电压可能跃变的电容支路的割集中 ,若除电容支路外的支路中无冲激电流存在 ,则电容电荷守恒 ,否则电容电荷有可能不守恒 ;若存在由纯电感和理想电流源构成的割集 ,则电感电流就有可能跃变 ,在含电流可能跃变的电感支路的回路中 ,若除电感支路外的支路中无冲激电压存在 ,则电感磁链守恒 ,否则电感磁链有可能不守恒。
The capacitive voltage would leap probably if there is a loop composed by only capacitors and ideal voltage sources when dynamic circuit is switching. In the cutset of capacitive branch in which voltage's leaping is possible, if there is no impulse current in those branches except for capacitive ones, capacitive charge is conservational, otherwise it may be not conservational. If there is a cutset composed by only magnetisms and ideal current sources, the magnetism current would leap possibly. In the loop of magnetism branch in which current's leaping is possible, if there is no impulse voltage in those branches except for magnetism ones, the magnetism chain is conservational, Otherwise it may be not conservational. The resolving method of circuit initial condition without capacitive charge's conservation or magnetism chain's conservation has been given in this paper.
