    Abstract: A diode is integrated on a semiconductor chip having anode and cathode surfaces opposite to each other. The diode comprises a cathode region extending inwardly from the cathode surface, a drift region extending between the anode surface and the cathode region, and a plurality of anode regions extending from the anode surface in the drift region. The diode further comprises a cathode electrode coupled with the cathode region, and an anode electrode that contacts one or more contacted anode regions of said anode regions and is electrically insulated from one or more floating anode regions of the anode regions. The diode is configured so that charge carriers are injected from the floating anode regions into the drift region in response to applying of a control voltage exceeding a threshold voltage.

    Abstract: A method controls a power factor correction converter that includes a boost inductor and a switch. The method generates a sense signal representing a rectified AC input voltage or an inductor current through the boost inductor, turns on the switch in response to determining, based on the sense signal, a zero current condition through the boost inductor, turns off the switch after an on-time interval, generates a feedback signal based on an output voltage of the converter, and compares the feedback signal with a threshold. If the feedback signal is smaller than the threshold, the method generates a command signal, representing a phase domain including 0 and π, based on the feedback signal and the power threshold, and keeps the switch off when a phase of the input rectified AC voltage or of the inductor current is in the phase domain even if the zero current condition has been determined.

    Abstract: A switching controller of a poly-phase electric motor may generate, in a fully digital manner, a replica of the phase current and/or of the phase (star) voltage of one or more windings of the motor. The switching controller may use digital signals already available for driving the motor to reconstruct a replica of the phase current or the phase voltage, and thereby avoid the need for dedicated analog components for phase current or phase voltage determination.

    Abstract: A method for the automatic design of an electronic circuit includes operations for evaluation of the thermal effects in the electronic circuit. The method generates a layout of the electronic circuit. Abstract data at the substrate level associated to the layout of the electronic circuit is then generated. A grid of partitioning is generated with respect to a view regarding the aforesaid abstract into meshes and nodes. The grid is applied to the substrate. On the basis of the grid (TG), a list of nodes or netlist representing a thermal network that represents the thermal behavior of the substrate or of its portions or elements is extracted. The netlist is useful in simulation operations, in particular of a SPICE type, for making an evaluation of thermal effects in the electronic circuit.
