This study proposed the nodal dynamic equation to solve the electromagnetic transient of linear switching circuit. The nodal dynamic equation is derived from the principle of energy conservation. By using trapezoidal method and time step to discrete the dynamic equation, its time discrete format is equivalent to the EMTP equation. Comparing with the EMTP method, the proposed method can change its numerical integration method and time step flexibly in the simulation. It is more suitable to solve the switching circuit.
