Abstract

Modeling and control of switched-mode dc-dc converters has occupied a center stage in the field of modern power electronics due to their applications in various industry. Average modeling is an effective tool to analyze dynamic behavior of a converter and are widely accepted in practice because of their simplicity, generality and demonstrated practical utility. However some fundamental questions regarding averaging methodologies still lack satisfactory answers. These unresolved modeling issues are related to their practical validation, inclusion of circuit parasitic. In this paper compensation factors have been proposed for making the model suitable for automatic control.
