Direct Buck-type AC-AC Converters using VSC Metod

The researches on direct AC-AC converters have been an important field. The DC-modulated method, which was used in DC-DC converters before, is used in AC-AC converters to realize a direct AC-AC converting now. The traditional control method regulates the output by adjusting the duty ratio. Its' core is the PWM technology. In this paper, the variable structure control (VSC) strategy was utilized in Buck-type AC-AC converters. The simulations and experiments proved that the VSC controller was more efficient and faster response. Streszczenie.
