Small-signal simulation applied to calculation of the parameters of nonlinear dynamics processes control systems for DC/DC converters

Abstract

The article discusses the issues of choosing the control system parameters for pulse-width DC/DC converters with the target-oriented control. This takes into account the nonlinear dynamic processes control system, which is important when constructing power conversion systems with increased requirements for speed. A nonlinear dynamic model of the system is developed taking fully into account the dynamic properties of the control system. A technique for selecting control system parameters based on small-signal modelling is proposed, which greatly simplifies the calculation process. The suggested approach can be applied in developing DC/DC converters of a wide class.
