Abstract: An electronic converter includes first and second inputs, first and second outputs, and a switching cell configured to supply current. The switching cell includes a half-bridge including first and second switches connected in series between the two inputs. The half-bridge includes a intermediate point between the first and second switch, a first inductor directly connected to the first output, a second inductor connected to the intermediate point, a first capacitor connected in series with the first and second inductors, a second capacitor connected between the intermediate point and the second input, and a circuit connected between a terminal of the first inductor and the second output. A circuit path of the converter is configured to couple the second inductor with the first output through the first capacitor and the first inductor, and another circuit path is configured to couple the second capacitor with the first output through the first inductor.

Abstract: A converter includes two switching stages coupled in series between positive and negative input terminals. A control circuit is configured for driving the switching stages based on an output voltage of the converter. A first switching stage includes two switches coupled in series between a positive input terminal and a first node. A capacitor and an inductor are coupled in series between the two switches and a positive output terminal. A third switch is coupled between a node between the capacitor and the inductor and the negative input terminal. A second capacitor is coupled between the first node and the negative input terminal. A second switching stage includes a second node coupled to the first node. Two additional electronic switches are coupled in series between the second node and the negative input terminal. A second inductor is coupled between the two additional switches and the positive output terminal.

Abstract: A method is provided for controlling a converter of the multiphase interleaving type. According to the method, there is detected when a change of the load applied to an output terminal of the converter occurs. All the phases of the converter are simultaneously turned off, and a driving interleaving phase shift is recovered so as to restart a normal operation of the converter. A controller for carrying out such a method is also provided.
