摘要： A control circuit for a switch unit of a clocked power supply circuit, the switch unit being designed to effect input-side excitation of a resonant transformer arrangement, comprises an input for receiving an auxiliary signal from the resonant transformer arrangement. The auxiliary signal exhibits an essentially fixed phase relation to a load alternating current flowing through a resonant circuit of the transformer arrangement. The control circuit further comprises a phase detector designed to detect reference crossing moments when the auxiliary signal crosses a predefined reference value, a driver controllable to switch the switch unit, and a synchronizer designed to synchronize a turn-on of the switch unit by the driver with regard to a phase position with the auxiliary signal so as to achieve a turn-on of the switch unit within a predetermined time interval around a zero crossing of a voltage present across the switch unit, or of a current flowing through the switch unit. The synchronizer is further designed to receive information about the reference crossing moments from the phase detector, and to provide a turn-on signal to the driver with a fixed phase delay at the reference crossing moments, so as to define turn-on moments at which the driver is to turn on the switch unit. The control circuit further comprises a detector designed to determine an amplitude information which depends on an amplitude or a mean value of the auxiliary signal, and a regulator designed to change an operating frequency in dependence on the amplitude information supplied by the detector, and to determine a period duration between turn-off moments at which the driver is to turn off the switch unit as a reciprocal of the operating frequency. An inventive resonance converter enables independent control of frequency and turn-on moments, or duty cycle, and thus enables a particularly efficient operation of the resonance converter, and a particularly precise regulation.

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 control circuit for a switch unit of a clocked power supply receives an auxiliary signal from a resonant transformer driven by the switch unit and detects reference crossing moments when the auxiliary signal crosses a reference value. A driver is controllable to switch the switch unit, and a synchronization circuit synchronizes a turn-on of the switch unit within a predetermined time interval around a zero crossing of a voltage present across the switch unit, or of a current flowing through the switch unit. The synchronization circuit receives information about the reference crossing moments and provides a turn-on signal to the driver with a fixed phase delay at the reference crossing moments, so as to define turn-on moments at which the driver is to turn on the switch unit.

摘要： The invention relates to a method for provision of a drive signal for a switch which controls the current drawn by an inductive energy storage element in a power factor correction circuit, in which a control signal which controls the power consumption is available. 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.

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.
