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