摘要： The invention relates to an LED converter for operating a load comprising at least one LED series that includes at least one LED, preferably multiple LEDs. On the primary side, the LED converter comprises a resonant converter supplied with a direct current voltage. The resonant converter has a half-bridge that is constructed of two reciprocally clocked switches and that provides a supply voltage for the LED series through a serial/parallel resonance circuit connected to the midpoint of said half-bridge. To regulate the power transferred by the LED converter to the LED series as a feedback factor in each switch-on cycle, a control unit is designed to directly or indirectly determine a peak value of the feedback factor through the lower-potential switch of the half-bridge and to adjust the clocking of the half-bridge, i.e. the frequency and/or the duty factor, as a control factor.

摘要： The invention provides an LED converter for operating a load comprising at least one LED series with at least one LED, preferably with multiple LEDs, wherein the LED converter on the primary side comprises a resonant converter supplied with a direct current voltage. Said converter has a half-bridge constructed of two reciprocally clocked switches and providing a supply voltage for the LED series through a serial/parallel resonance circuit connected to the midpoint of said bridge. The LED converter has a control unit that is arranged for adjusting the clocking frequency of the half bridge. To control or regulate the power transferred by the LED converter to the LED series, the control unit is arranged to vary the frequency of the clocking in a frequency corridor that is delimited on at least one side, and to vary the amplitude of the direct current voltage supplying the resonant converter if a change of the load and/or the change of a setpoint value for the power would lead to a frequency operating point outside the frequency corridor.

摘要： The invention relates to a method for activating at least one LED, which is supplied with a direct current voltage or a rectified alternating current voltage and which by means of a coil (L1) and a first switch (S1) clocked by a control/regulating unit (SR) provides a supply voltage for at least one LED, wherein when the first switch (S1) is switched on the coil (L1) temporarily stores energy that discharges via a diode (D1) and at least one LED when the first switch (S1) is switched off and wherein the control unit (SR) activates the first switch (S1) by means of a dimming signal. Said method is characterised in that the dimming signal is generated by externally combining a low-frequency signal and a high-frequency signal, wherein the pulse width (TON*LF) of the low-frequency signal is selected as an integral multiple of the cycle duration of the high-frequency signal.
