Abstract

Official abstract text for this publication.

Driver circuits ( 1 ) for driving load circuits ( 2, 3 ) receive source signals from sources and provide feeding signals to the load circuits ( 2,3 ) and charging signals to capacitor circuits ( 21 ). These capacitor circuits ( 21 ) provide supporting signals to the load circuits ( 2, 3 ) in addition to the feeding signals. By providing the driver circuits ( 1 ) with control circuits ( 22 ) for controlling the supporting signals, the capacitor circuits ( 21 ) can become less bulky/costly and/or will limit the lifetime of the driver circuits ( 1 ) to a smaller extent. Further, these driver circuits ( 1 ) may get improved efficiencies. Said controlling may comprise controlling moments in time at which the supporting signals are offered to the load circuits ( 2, 3 ) or not, and/or may comprise controlling sizes of the supporting signals, and/or may be done in response to detection results from detectors ( 23 ) for detecting parameters of one or more signals. Said controlling may comprise switching via switches ( 24 ).

First claim

Opening claim text (preview).

The invention claimed is: 1. A device including a driver circuit for driving a load circuit, the driver circuit comprising: an input terminal configured to receive a source voltage from a source and to provide a feeding current and a charging current, a capacitor circuit configured to receive the charging current and to provide a supporting current, an output terminal configured to receive the feeding current and the supporting current and to provide the feeding current and th…
