Abstract

The invention relates to a method for modifying network state equations of circuits according to switch states. The method comprises the following steps of: (1) writing a system state equation of a circuit; (2) enabling an ideal switch in the circuit to be equivalent to a basic branch element; and (3) modifying the system state equation of the circuit. According to the method provided by the invention, the state equation of the circuit is modified according to the on and off states of the ideal switch in the circuit; and compared with the traditional circuit analysis method, the method does not need to regenerate a circuit equation and only needs to modify the branches undergoing switch state switching, so that the calculation speed of the method is considerably higher than the calculation speed of the existing circuit analysis method.

Description

technical field [0001] The invention relates to a method for modifying a circuit system state equation, in particular to a method for modifying a circuit network state equation according to a switch state. Background technique [0002] When there is an ideal switch in the circuit, the switching of the switch state will cause the change of the circuit topology. The commonly used node analysis method needs to add a new node (when the switch is open) or merge two nodes (when the switch is closed) when dealing with the switch action, which will cause changes in the number of nodes in the circuit, and the circuit needs to be rewritten equation. Theoretically, when there are n switches in the circuit, there are at most 2 n It will bring a very large workload to write the equations of these different topologies. [0003] The invention patent "A Method for Listing the State Equation of a Circuit Network" provides a method for writing the state equation of a general linear circuit...
