Abstract: An AC/DC converter includes a first terminal and a second terminal to receive an AC voltage and a third terminal and a fourth terminal to deliver a DC voltage. A rectifying bridge is provided in the converter. A controllable switching or rectifying element has a control terminal configured to receive a control current. A first switch is coupled between a supply voltage and the control terminal to inject the control current. A second switch is coupled between the control terminal and a reference voltage to extract the control current. The first and second switches are selectively actuated by a control circuit.

Abstract: A rectifier bridge circuit includes a first SCR/IGBT switch and a second SCR/IGBT switch coupled to a circuit input to receive an ac input voltage. The first and second SCR/IGBT switches are alternatively switchable to generate a rectified voltage at a circuit output. Control currents coupled to control terminals of the first and second SCR/IGBT switches are power supply sourced from an auxiliary dc source generated by rectifying the ac input voltage. The control currents are generated by current sources coupled between the auxiliary dc source and the control terminals of the first and second SCR/IGBT switches. The current sources are selectively activatable to produce gating currents for switching on and off the first and second SCR/IGBT switches. A controller unit is provided to control the current sources via level shifter circuits. The control implements progressive conduction time of the first and second SCR/IGBT switches so as to provide inrush current limitation.

Abstract: A power supply apparatus includes a power supply circuit and a power-on circuit. The power-on circuit detects a remotely transmitted control signal and causes a transition of the power supply circuit to a turned on state. The power-on circuit includes a transducer configured to provide a power-on signal in response to the remote control signal. The transducer triggers transition to the turned on state through a switch driven by the power-on signal output from the transducer and arranged to supply a power supply circuit enable signal. A DC blocking capacitor is connected between an output of the transducer and a control terminal of the switch.

Abstract: Radiofrequency energy that is captured by a radiofrequency power harvester is stored in a storage capacitance. One or more user circuits are supplied with energy stored in the storage capacitance. The harvester operates in alternated charge and burst phases with captured radiofrequency energy stored in the storage capacitance in the charge phases and supplied to the user circuits in the burst phases to perform user circuit tasks. In response to detection of completion of the user circuit tasks in a burst phase, the harvester causes operation to shift to the next charge phase.
