This paper describes an analysis of the transient response of an orthogonal core-type dc-ac converter for use in a photovoltaic power system. The analysis is based on a numerical model of an orthogonal core for use with the SPICE circuit analysis program. As one example of such a transient response analysis, we calculated the voltage and current of the dc-ac converter when its secondary is cut off from the ac system. The calculated results agreed well with measurements. The analytical method presented here is useful for predicting the behavior of a photovoltaic power system at the occurrence of ac system interaruptions, line-to-line faults and various other faults.
