Discovering New Topologies

This is a journey into the world of new topologies and related techniques. It starts with a discussion of synchronous Buck and Boost topologies and shows how in complementary drive mode, they transform automatically from one to the other as the average inductor current passes through zero. Diode emulation mode is discussed along with dead time concerns and the beneficial effects of placing a Schottky diode in parallel to a synchronous FET. A detailed explanation and derivation of DCR sensing and lossless droop regulation (voltage positioning) is presented along with innovative ideas like the inductorless Buck and an unusual method of droop regulation. Next, composite topologies are discussed starting with ...
