A tensão de circuito aberto (OCV) de dispositivos elétricos é um problema em diversas áreas, cuja avaliação numérica necessita de tratamento cuidadoso. A estrutura em circuito aberto está mal condicionada devido ao campo elétrico singular nos cantos, e a componente TEM do campo elétrico deve ser extraída antes de integrada para fornecer a tensão no método direto de obtenção do OCV. Este artigo apresenta os métodos indiretos para cálculo do OCV, o método da matriz de admitância e o método do teorema de Norton. Ambos os métodos são baseados na estrutura em curto-circuito que está bem condicionada. As expressões explícitas do OCV são derivadas em termos dos elementos da matriz de admitância no método da matriz de admitância, e em termos da corrente de curto-circuito e da impedância da antena do dispositivo elétrico em consideração no método do teorema de Norton. Esses dois métodos são equivalentes em teoria, mas o método da matriz de admitância é adequado para casos de transmissores próximos, enquanto o método do teorema de Norton é adequado para casos de transmissores distantes. Vários exemplos são dados para mostrar a utilidade da presente teoria.

Abstract: Open circuit voltage (OCV) of electrical devices is an issue in various fields, whose numerical evaluation needs careful treatment. The open-circuited structure is ill-conditioned because of the singular electric field at the corners, and the TEM component of the electric field has to be extracted before integrated to give the voltage in the direct method of obtaining the OCV. This paper introduces the indirect methods to calculate the OCV, the admittance matrix method and the Norton theorem method. Both methods are based on the short-circuited structure which is well-conditioned. The explicit expressions of the OCV are derived in terms of the admittance matrix elements in the admittance matrix method, and in terms of the short circuit current and the antenna impedance of the electrical device under consideration in the Norton theorem method. These two methods are equivalent in theory, but the admittance matrix method is suitable for the nearby transmitter cases while the Norton theorem method is suitable for the distant transmitter cases. Several examples are given to show the usefulness of the present theory.

AB - Open circuit voltage (OCV) of electrical devices is an issue in various fields, whose numerical evaluation needs careful treatment. The open-circuited structure is ill-conditioned because of the singular electric field at the corners, and the TEM component of the electric field has to be extracted before integrated to give the voltage in the direct method of obtaining the OCV.

Both methods are based on the short-circuited structure which is well-conditioned. The explicit expressions of the OCV are derived in terms of the admittance matrix elements in the admittance matrix method, and in terms of the short circuit current and the antenna impedance of the electrical device under consideration in the Norton theorem method.
