“…In the first case the target is to increase the features of traditional on load tap changers using new configuration as regard the windings and the electric circuits used during switching process [8], [9]. The new solutions to maintain a constant voltage level to customers, mean to use power semiconductors commanded by microcontroller [10], [11], the ferroresonance phenomenon [12], or to use the orthogonal magnetization concept with the aim to get a variable inductance and the possibility to control the secondary voltage of power transformers [ 1 3], [14].…”

At many industrial automatization processes, measurement and control installations and also at network PCs it is necessary to supply different types of electrical devices with voltage level between certain admissible limits. It is very important that the voltage level not to be depended by external variations such as: supply voltage, frequency and load. Therefore, a new device based on a data acquisition board has been proposed. This new device allow to maintain the output voltage from power transformers between admissible limits both at voltage increasing or decreasing. The voltage acquisition, analysis and output control signals is achieved using a data acquisition board programmed with the LabVIEW software. The prototype has been tested at load variation and input voltage variation on power transformer side. In both situations the new device has maintained the voltage level between admissible limits.
