Abstract
This paper presents the theory and implementation of the non-linear control method of Input to Output Linearization (IOL) for boost DC-DC switching power converters operating in continuous inductor current mode. The paper examines the non-linear and non-minimum phase nature of boost converters. The limitations of IOL control on boost converters have been outlined. It has been shown that these limitations are overcome by addressing the non-minimum phase nature in boost converters. Using analytical and experimental methods, it is demonstrated that IOL control scheme compensates the non-linear boost converter to achieve wide range of output voltages with excellent response to load and duty cycle variations.
