Document Type and Number:
Japanese Patent JP2519195
Kind Code:
B2
Abstract:
According to a process for controlling a voltage transformer having a wide input voltage range for full sine mains current consumption, the input current of the voltage transformer is controlled or regulated in dependence on a current set value. The output voltage of the voltage transformer serves a a real input value for a regulator that generates a regulating signal in dependence on an output voltage set value. Said current set value is obtained by multiplying a signal that is proportional to the rectified input voltage of the voltage transformer by said regulating signal, as well as by a direct voltage signal that is inversely proportional to the peak value, the effective value or the mean value of the input voltage of the voltage transformer. This process is preferably used in a clocked voltage transformer, such as a blocking oscillator type converter, a high-pass or a high-low pass transformer.
