Abstract: DC/DC converters, which have a quadratic term of the duty cycle, are useful, when wide voltage transformation ratios have to be obtained. Taking a d-square step-down converter as an example, the function of the converter, the generation of the large and small signal models is explained. From the voltage transformation ratio, a control law is derived and the behavior of the feed-forward converter is shown by simulations. Results of two other quadratic converters are also shown.
