摘要： In an electronic ballast the output d.c. voltage (U) of a PFC intermediate circuit (3) is to be regulated. The intermediate circuit (3) has a clocked switch (S) which is controlled by a regulation circuit (7). The regulation circuit (7) includes two counters (Z1, Z2). The counter (Z1) has a greater number of count stages than the counter (Z2). The counter (Z1) is counted upwards or downwards in dependence upon the regulation difference. The counter (Z2) is repeatedly counted only in one direction and for example reset by means of a reset signal. By means of comparison the counts of corresponding count stages of the two counters (Z1) and (Z2) in a comparator, the switch on time (ton) for the clock switch (S) is determined.

摘要： In an operating circuit for a gas discharge lamp 1, in particular in the aeronautical field, an inductance L1 is connected upstream of the gas discharge lamp 1 and a switch V3 periodically controlled by an electronic control system 3 controls the current through the inductance L1. In order also to be able to achieve very low dimming values with freedom from flicker, by virtue of the switch V3 being switched into a conducting condition by means of the electronic control system 3 a constant dc voltage Uin is applied to the inductance L1 for a constant switch-on duration ton. By the switch V3 being switched off at the end of the switch-on duration ton the energy stored by the inductance L1 is discharged to the gas discharge lamp 1. In each case after discharge of the inductance L1 the electronic control system 3 closes the switch V3 periodically again for the switch-on duration ton.

摘要： A dimmable LED power supply circuit arrangement is disclosed. The circuit arrangement includes a flyback converter coupled between an input for receiving a rectified alternating line voltage and an output providing power for at least one LED device. The flyback converter includes a transformer and a semiconductor switch for switching a primary current of the transformer. A current sensing unit provides a current sense signal dependent on the primary current. A control unit controls the switching operation of the semiconductor switch dependent on the rectified alternating line voltage and the current sense signal such that the flyback converter operates in a quasi-resonant mode of operation, whereby the current sense signal is compared with a time-varying reference signal representing the rectified alternating line voltage and whereby a switch-off time of the semiconductor switch is determined dependent on the comparison.

摘要： In a circuit configuration to operate a gas discharge lamp (LA) the lamp (LA) is arranged in a full bridge circuit. A control circuit in normal operation actuates the four switches (S1-S4) in such a way that it changes over with a first frequency (f1) alternately between a first and a second state (T1, T2), whereby in the first state (T1) the two switches (S2, S3) of a first bridge diagonal are opened, one switch (S1) of the second bridge diagonal is closed and the other switch (S4) with a second frequency (f2), which is higher than the first frequency (f1), is alternately opened and closed. In the second state (T2) the four switches (S1-S4) are actuated in such a way that the lamp (LA) is pole reversed. In a start phase (TS) on the contrary the switch connected to the DC voltage source (S4) of a half-bridge is opened, the second switch (S3) of this half-bridge is closed, and the two switches (S1, S2) of the other half-bridge are with a third frequency (f3) alternately opened and closed. As a result reliable lamp starting is rendered possible and at the same time the generation of high-frequent alternating fields in normal operation is reduced.
