In this paper, We describe a numerical model of a bridge-connected magnetic circuit for use in SPICE. The model was devised on the basis of a bridge-connected magnetic circuit with saturation and hysteresis effects. As an example of the application of its SPICE model, We analyzed the transient behavior of the power-measuring circuit caused by the principle of magnetic oscillation, using a bridge-connected magnetic circuit and a saturable core. The calculated results agree well with the measured ones. A SPICE model of the bridge-connected magnetic ciruit presented here is useful for the analysis and design optimization of the power-measuring circuit.
