Abstract :
The author describes the work which has been done on the steady-state mathematical model for the DC-AC inverters for the US Space Shuttle. The mathematical model is based on input/output data which describe the operation of the DC-AC inverters. Two methods of modeling were used, namely, the least-squares method and a method using a set of orthogonal polynomials. The reason for this mathematical model of the DC-AC inverters was to provide a computer program which could be used by the Electrical Power Distribution Lab. at the Johnson Space Center for simulation of steady-state operations. These data were modeled to produce a set of equations which approximate the output conditions and also some of the input conditions. These equations were then incorporated into a computer program written in Pascal
