摘要： A resonant converter includes : - an insulation transformer (T) with a primary winding and a secondary winding, said transformer having a magnetizing inductance, - first (C1) and second (C2) capacitors coupled to the primary winding of the insulation transformer (T) to form with said magnetizing inductance a first and a second branch of a resonant circuit, and switching elements (Q1, Q2) to apply to the primary winding a positive alternate drive signal, whereby the first branch of the resonant circuit is traversed by a current to produce energy transfer to the secondary winding of the insulation transformer (T). Protection of the converter against overload is provided by sensing (10) any current flow in the second branch of the resonant circuit to turn off (16) the converter when the second branch of the resonant circuit is traversed by a current.

摘要： A drive arrangement for light sources (L) such as LEDs includes a connection line (14) to transmit feeding power towards a light source (L), a switch element (16) coupled to the line (14) to apply on/off signals to the line (14), and a controller (18), such as a microcontroller, to control operation of the switch (16). The controller is sensitive to a dimming signal (DS) representative of a desired dimming level for the light source (L) and an information-carrying digital signal (DF). The controller is configured to control operation of the switch (16) to: - a) PWM modulate an on/off signal applied to the connection line (14) as a function of the dimming signal (DS) so that the average current of the PWM modulated on/off signal applied to the connection line (14) controls the brightness of the light source (L), b) transmit the information-carrying digital signal (DF.) as an on/off information signal applied to the connection line (14), so that the information carried by the information-carrying digital signal (DF) is transmitted over the connection line (14).
