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.

摘要： A circuit configuration for limiting an output voltage of a clocked voltage regulator includes a control unit receiving a direct voltage to be regulated and having an output for supplying an output voltage. A voltage regulating amplifier is constructed as an integrator, receives the output voltage and a reference voltage, and supplies an output signal. A current threshold generator detects a current intensity of the integrator and supplies an output signal. A multiplier multiplies the output signal of the current threshold generator by the output signal of the voltage regulating amplifier and a signal obtained from the direct voltage to be regulated and supplies an output signal. A current regulating amplifier receives the output signal of the multiplier and a signal obtained from the direct voltage to be regulated and supplies an output signal. A driver stage converts the output signal of the current regulating amplifier into a trigger signal for the control unit. A comparator detects an output voltage of the voltage regulating amplifier and furnishes a dominant shutoff signal to the control unit if a reference voltage is exceeded.

One drive cycle of the switch comprises: detection of a predetermined storage state of the inductive energy storage element; when the predetermined storage state of the storage element is detected, production of a switching-on level for the drive signal for a regular switched-on duration which is dependent on the control signal or for a maximum switched-on duration which is dependent on an input voltage, when the regular switched-on duration is greater than the maximum switched-on duration; and production of a switching-off level for the drive signal for a switched-off duration until the next detection of the predetermined storage state.
