摘要： An energy scavenging device includes an electromagnetic transducer adapted to generate a current in response to accelerations impressed thereto. The device also includes a power switching stage input with the current generated by the electromagnetic transducer, having a network of controlled switches adapted to alternately deliver on output nodes of the switching stage an output current that does not invert its sign and to short-circuit the transducer. There is an output capacitor coupled between the output nodes of the power stage. A controller having a sensor coupled to the electromagnetic transducer is to sense the current flowing therethrough, the controller being adapted to drive the switches of the power stage in order to either short-circuit the electromagnetic transducer or to direct the current flowing through the transducer to charge the output capacitor.

摘要： A switching voltage regulator control device, includes first and second half-bridges each comprising a switch. The first half-bridge is located between an input voltage and a reference voltage and the second half-bridge is located between an output voltage and the reference voltage. The regulator comprises a detector for detecting the error between a reference voltage representative of the output voltage and another reference voltage and an integrator for integrating said error. The control device is suitable for providing a first duty cycle for driving the switch of the first half-bridge that is proportional to the integrated error divided by the input voltage and a second duty cycle for driving the switch of the second half-bridge that is proportional to the value of the input voltage divided by the integrated error.

The driving circuit includes an output transistor coupled between a voltage reference and the output terminal, a high voltage comparator coupled to said output terminal and to a threshold voltage reference), a start-up circuit controlled by a setting signal; and a switching ON/OFF circuit having an input coupled to the start-up circuit an input coupled to the comparator, and an output coupled to a control terminal of the output transistor. The start-up circuit provides an ON signal to the switching on/off circuit and the comparator provides an OFF signal to the switching on/off circuit which switches off the output transistor. The high voltage comparator generates the switching off signal in response to the output voltage reaching a desired supply voltage value which depends on the value of the first threshold voltage reference.
