Abstract: Disclosed herein is a voltage converter including input nodes configured to receive an input voltage, output nodes configured to deliver an output voltage, a rectifying bridge coupled between the input nodes and the output nodes, a capacitor and a resistor series-coupled between the output nodes, and a thyristor coupled between one terminal of the resistor and a given one of the output nodes, wherein the thyristor is configured to allow flow of a positive current from the resistor to the given one of the output nodes. A control input is configured to receive a control signal, wherein the control signal biases a gate of the thyristor to control the flow of current through the thyristor. transient voltage suppressor circuit is coupled to the gate of the thyristor, configured to activate the thyristor upon exceeding a threshold voltage.

Abstract: A method for manufacturing electronic chips includes forming, on the side of a first face of a semiconductor substrate, in and on which a plurality of integrated circuits has been formed beforehand, metallizations coupling contacts of adjacent integrated circuits to one another. The method further includes forming, on the side of the first face of the substrate, first trenches extending through the first face of the substrate and laterally separating the adjacent integrated circuits. The first trenches extend through the metallizations to form at least a portion of metallizations at each of the adjacent circuits.

Abstract: A control device includes a triac and a first diode that is series-connected between the triac and a first terminal of the device that is configured to be connected to a cathode gate of a thyristor. A second terminal of the control device is configured to be connected to an anode of the thyristor. The triac has a gate connected to a third terminal of the device that is configured to receive a control signal. The thyristor is a component part of one or more of a rectifying bridge circuit, an in-rush current limiting circuit or a solid-state relay circuit.

Abstract: A circuit includes two input nodes and two output nodes. A rectifier bridge is coupled to the input and output nodes. The rectifier bridge includes a first and second thyristors and a third thyristor coupled in series with a resistor in series. The series coupled third thyristor and resistor are coupled in parallel with one of the first and second thyristors. The first and second thyristors are controlled off, with the third thyristor controlled on, during start up with resistor functioning as an in in-rush current limiter circuit. In normal rectifying operation mode, the first and second thyristors are controlled on, with the third thyristor controlled off.

Abstract: A device includes a semiconductor substrate. A step is formed at a periphery of the semiconductor substrate. A first layer, made of polysilicon doped in oxygen, is deposited on top of and in contact with a first surface of the substrate. This first layer extends at least on a wall and bottom of the step. A second layer, made of glass, is deposited on top of the first layer and the edges of the first layer. The second layer forms a boss between the step and a central area of the device.
