Abstract

This thesis develops a model of a nonlinear self oscillating current-or-voltage step-up dc-to-dc converter. Expressions are given that predict the operation of the converter in the time domain and in the state plane. To verify these expressions, a large signal computer simulation technique [1] is used to compare theoretical results with actual measurements. This type of simulation allows a nonlinear switching converter to be modeled with a series of piecewise-linear operating intervals. The resulting waveforms predicted by the developed model show close agreement with waveforms found in the laboratory. Therefore, the model represents a powerful tool that may be used to aid in optimizing the converters performance.
