C'uk Converter Design A C'uk converter has an input of 12 V and is to have an output of - 24 V supplying a 60 W load. Select the duty ratio, the switching frequency, the inductor sizes such that the change in inductor currents is no more than 12 percent of the average inductor current, the output ripple voltage is no more than 1.5 percent, and the ripple voltage across C1 is no more than 3 percent.
