A REVIEW OF BOOST CONVERTER ANALYSIS AND DESIGN IN AEROSPACE APPLICATIONS

Often, for simplicity, it is adopted for boost converter inductor and capacitor design the inductor current variation (∆IL), defining it as an output current percentage.However, this kind of methodology does not guarantee the inductor and capacitor minimum values that assure the converter working on continuos mode operation, discontinuos mode operation, or when it is desired to operate the converter at the boundary between these modes. The aim of this paper is to present a theoretical study of the no-losses boost converter. The principle of operation and static analysis are developed in detail for operation on the following modes: continuos mode operation, discontinuos current mode operation and at the boundary between these modes. During this analyses, all four variables (input and output currents and voltages) are considered as design choices for independent variables that determine the boundary between continuos and discontinuos modes. In addition, a design methodology is presented to ilustrate the theoretical procedures, which guarantee the inductor and capacitor minimum values according to the desired operation mode. Finally, the simulation results proof the theroretical analysis.
