Modular transformer state model for the simulation of high frequency spacecraft power systems
Abstract
A high frequency, lumped parameter model of a power transformer is presented. The model is used to derive a third-order state variable description of the device that is coupled to state variable models of the other power system components. Based on the state model, a digital simulation is conducted using the state transition matrix. The technique is used to simulate a high frequency spacecraft power system which includes a series resonant converter, transformer, transmission line, and resistive-inductive load. Each individual device is modeled as a two-port modular subnetwork with port voltages used as the independent variables. A state variable mathematical description of each device is formulated and numerically simulated using the state transition matrix. The results of the simulation are compared to results from EMTP, a program widely used by the power industry to predict transients.
