A general computer aided tool to assess the impact of component value tolerance on power supply performance

A computer-based tool for checking the effects of component value variation within a specified tolerance range is discussed. A model-building process is described for handling the single nonlinear equation that describes the investigated system over one complete cycle. Perturbation and subsequent linearization of the equation are used to obtain a linear continuous system for an 'averaged' system model. This procedure is used for the analysis of a full-bridge converter circuit.<
