Abstract: A switched-mode converter includes first and second chopper transistors, and control means for maintaining the first and second chopper transistors respectively on and off during first operating phases. The first and second chopper transistors are maintained respectively off and on during second operating phases. An intermediary voltage is applied to the gate of the second transistor during intermediary phases taking place between the first and second phases. This intermediary voltage is close to the threshold voltage of the second transistor.

Abstract: Systems and methods for compensating ripple current and improved ripple compensators and switching converters capable of compensating ripple current. In one embodiment, the ripple compensator for a switching converter of the type includes a switching means and filtering means comprises means for injecting a compensating current such that the AC component of the switching current and the compensating current are in opposite phase. In addition, the compensation current is elaborated from a signal at a node between the switching means and the filtering means.
