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： 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.
