The article presents the work of the stepless hybrid distribution transformer (HT), as an alternative to the so far applied Automatic Voltage Regulator (AVR) solutions, used to control the voltage in the power system in terms of the fundamental harmonic. The HT is a combination of a conventional distribution transformer and an AC/DC/AC converter connected in series with the transformers secondary winding. In the work the basic control algorithm of the AC/DC/AC converter operated as a series connected additive voltage source in the HT system, has been described. The article contains the preliminary results of computer simulation studies of the model elaborated in PSIM.
