It is an algorithm that can automatically create circuit equations for any circuit.
Why can circuit simulators represented by SPICE freely simulate any circuit? In the circuit analysis learned in school, a specific circuit is given, and the analysis procedure is considered while looking at the circuit diagram. There is no concept of 'solving any circuit' here. However, to put it another way, the process of looking at the circuits in a problem set and constructing simultaneous equations can be replaced by programming, which means solving any circuit. The nodal analysis method is an algorithm that can automatically create circuit equations for any circuit based on certain rules. 【Features】 ○ The nodal analysis method establishes nodal equations at each node based on Kirchhoff's law, which states that 'the sum of currents flowing into a point is zero.' ○ A node is considered as a single point representing parts with the same potential.

basic information
【Rules for Matrix Generation】 ○ The elements of Gij (i=J) are the sum of the element values (admittance) connected to that node. ○ The elements of Gij (i≠j) are the sum of the element values (admittance) connected between those nodes, multiplied by -1. ○ Furthermore, when considering only current elements, the matrix becomes a symmetric matrix. The size of the matrix will be equal to the number of nodes. ● For more details, please contact us or download the catalog.
