Control process for a voltage transformer with a wide input voltage range and the application of such a process |
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.
