摘要： For monitoring the operation of a gas discharge lamp operated with an AC voltage, a lamp voltage signal is generated which is dependent on the voltage dropped across the gas discharge lamp during operation. The lamp voltage signal is filtered with an attenuation that is different for a DC component and for a component having the frequency of the AC voltage, whereupon a positive and negative peak value of the filtered lamp voltage signal are determined. For monitoring the gas discharge lamp, an average value of the two peak values is determined and compared with a limit value, and a difference value between the two peak values is determined and compared with a limit value.

摘要： The present invention relates to a protection circuit for protecting a half-bridge circuit. The protection circuit detects an incorrect response of the half-bridge by monitoring the current of a first switch at a series resistor of a second switch. The protection circuit has a detector for detecting the voltage across the resistor and an evaluation circuit which is designed in such a manner that it evaluates an output signal from the detector after the first switch has been switched on and provides a fault signal at an output when the voltage across the resistor is greater than the threshold voltage.

摘要： The document describes a method and an actuating circuit for actuating a switch regulating the power consumption in a power factor correction circuit which has input terminals for applying an input voltage and output terminals for providing an output voltage. In this case, the switch is cyclically turned on for an on-time and turned off for an off-time, respectively, with the on-time having a first on-time period and a second on-time period which is directly adjacent to the first on-time period. A length for the first on-time period is in this case dependent on the control signal, and a length for the second on-time period is proportional, at least for a prescribed range of values for an instantaneous value of the input voltage, to a quotient with a first first-degree function for this instantaneous value in the denominator and a second first-degree function for the instantaneous value in the numerator, with function values for the first function increasing as the instantaneous value rises.
