Abstract: A circuit arrangement for operating light sources includes input terminals for a power supply system voltage, a first rectifying circuit, a boost converter having output terminals, a half-bridge arrangement having two switches, which is connected to the output terminals of the boost converter, an inductance, the first terminal of which is coupled to the centre point of the half-bridge, and a second rectifying circuit, the first input terminal of which is coupled to the second terminal of the inductance and the second input of which is coupled to one of the output terminals of the boost converter. The output terminals of the second rectifying circuit are coupled to the inputs of a current-compensated inductor. At least one light source is connected to the output terminals of the current-compensated inductor, and the output terminals of the current-compensated inductor are coupled to an output terminal of the boost converter via filter capacitors.

Abstract: In various embodiments, a switched-mode power supply is provided. The switched-mode power supply includes at least two output stages. Each output stage has a converter. A frequency of at least one of the output stages is modulated by way of a modulation unit configured to provide a modulation signal that is combined with a switching signal for driving a switching element of the converter of the at least one output stage.

Abstract: Various embodiments provide a wirelessly programmable electronic control gear, which may include an essentially enclosed metal or metallized housing. The housing is a punched and curved sheet-metal housing. The wirelessly programmable electronic control gear may further include a circuit board with an antenna component fitted thereon to receive wireless programming signals, and an area in the metal or metallized housing which has at least one longitudinal recess. The at least one recess is located close to the antenna. The orientation of the longitudinal recess is designed as essentially parallel to magnetic field lines of the antenna.
