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.

摘要： A switched-mode power supply for compensating for fluctuations in a feed voltage includes at least one electronic switch and a control circuit with a frequency generator, a comparator circuit, and a trigger circuit. The trigger circuit furnishes a trigger signal for the electronic switch as a function of an output signal of the comparator circuit and an output signal of the frequency generator. The comparator circuit has a switching threshold being defined as a function of a load current of the switched-mode power supply. The comparator circuit has a signal input being triggered with a periodically rising and falling control signal having a frequency defined by the frequency generator. The control signal has a signal shape being varied as a function of an instantaneous value of a feed voltage of the switched-mode power supply. In a method for anticipatory control of the power supply for compensating for feed voltage fluctuations, the control signal has a direct component and an alternating component, and only the direct component of the control signal is varied as a function of fluctuations of the feed voltage of the power supply.

摘要： A control process for a voltage transformer for sine-wave line current input with a large input voltage range, includes controlling or regulating the input current of the voltage transformer as a function of a current command value. The output voltage of the voltage transformer is in the form of an actual value input quantity of a controller which supplies a control signal as a function of an output voltage command value. The above-mentioned current command value is obtained by multiplying a signal proportional to the rectified input voltage of the voltage transformer by the above-mentioned control signal, and also by a direct current voltage signal which is a reciprocal of the peak value, to the effective value or to the average value of the input voltage of the voltage transformer. Such a process is preferably used in a switched-mode voltage transformer, e.g. in an isolating transformer, a step-up transformer or a step-up/step-down transformer.

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.
