I...An original Z transform-based algorithm is used to develop a fast and accurate tool for the dynamic analysis of switch-mode power converters and to achieve insight into the effect of each parasitic. It is shown that iron losses can be neglected without impairing the compliance in the analysis of all the single-inductor converters and also of the two-inductor converters without magnetic coupling. These losses must be included in the modeling of coupled inductor converters, since their effect on the control-to-output gain can jeopardize the feedback loop stability. Experimental data for a low-power prototype are reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>Read More
