Modeling of step-up dc-dc converters to formulate design guidelines for optimization

This paper provides guidelines in the form of a sequence of steps for optimization of step-up DC-DC converters using models derived from first and second order circuit equations. The models have been developed for three degrees of damping in the solution of the second order differential equation. Design issues for each case are discussed to obtain an optimized design. With specifications of input voltage, output voltage and power provided, the designer can employ the models to select appropriate component values and optimize circuit performance.
