Abstract
A buck converter, boost converter or flyback converter is generally represented as a two-port having a primary side with a primary switching device (10; 38; 70; 98; 110), and a secondary side with a secondary switching device (20; 50; 80; 106). The primary switching device is controlled in such a way that the on-time is adapted to the voltage at the primary side of the converter. The relation between the on-time of the primary switching device and the primary voltage is a generally hyperbolic function.
