Abstract: The present invention relates to a device (200, 800) for active balancing of a battery (B), the battery (B) comprising a plurality of units (U1-UN) connected in series at a plurality of nodes (N1-NN?1), the device comprising at least one DC/DC converter (210, 610, 710, 8101-810N) configured to transfer charges between a first group (G1) of the plurality of units (U1-UN) and a second group (G2) of the plurality of units (U1-UN), at least one of the first group (G1) and second group (G2 comprising a plurality of the units (U1-UN).

Abstract: A capacitive sensing system based on projected self-capacitance is suitable for use in printing systems/products to sense paper tray status. In example embodiments, a capacitive sensing system is adapted for sensing the condition/characteristics of paper in the paper tray, such as paper size, stack height and page count and paper dielectric. The capacitive sensing system can be configured with one or more shielded capacitive sensors incorporated into the paper tray, and oriented relative to the paper according to the paper condition/characteristic sensed.

Abstract: The present invention concerns a single stage inverter device for power converters, comprising switching means (M1-M4) capable to periodically connect an energy source, in particular a photovoltaic one, to an electric network or grid, the switching means (M1-M4) being controlled by controlling electronic means operating according to a single switching cycle control of the switching means (M1-M4), the operative and circuit device parameters being such to fulfill a series of constraints simultaneously optimizing both the maximum power point tracking or MPPT (Maximum Power Point Tracking) and the output power factor or PF-out (Power Factor-output) for one or more operation conditions. The present invention further concerns the related method of controlling and the related method of scaling such device.
