Abstract
The invention relates to a switched converter, comprising: at least one switch, output terminals for supplying an LED load, a capacitor arranged in parallel to the output terminals, a sensing transformer, a primary winding of the sensing transformer, a secondary winding of the sensing transformer; and a control circuitry controlling the operation of the at least one switch. The switched converter is configured to operate in alternating cycles between phases of supplying energy from a node on a potential of the at least one switch to the output terminals and phases of supplying energy to output terminals of the capacitor but not from said node. The primary winding of the sensing transformer is switched in series to the capacitor and the secondary winding of the sensing transformer is configured to generate an output signal supplied to the control circuity of the switched converter, wherein the control circuity is configured to sense the current flowing across the output terminals supplying the LED load based on said output signal.
