Abstract: Changes of reactive power will lead to voltage fluctuations in power system. In order to adjust reactive power, there is a need to have voltage adjustment, and power transformer on-load tap-changer is an important means for voltage adjustment. Via analysis of working principle and on-load tap-changer voltage adjusting process of different kind of on-load tap-changers, comparisons were carried out for mechanical type, power electronic type and hybrid type, their advantages and disadvantages summarized. Introduction was made to structures and existing technical difficulties in realization for three kinds of hybrid type on-load tap-changers, which provided reference for further carrying out hybrid type on-load tap-changer study.
       Key words: on-load tap-changer; mechanical; power electronic type; hybrid
