Derivation of the Brayton–Moser equations from a topological mixed potential function☆

A topological mixed potential function, P*T, is defined and shown to be an exact differential. From P*T, the Brayton-Moser equations are obtained from topological relationships of the network and the constitutive relationships of the elements. A relationship between P*T and Brayton-Moser's mixed potential function, Q, is developed.
