The utility model discloses a realize variable stage switching capacity type AC-AC converter of 12n transformation ratio. Mainly cascade in proper order by a plurality of basic element circuit and constitute: every basic element circuit includes three electric capacity and four power switch of establishing ties in proper order groups of group, power switch pipe that power switch group of every group establishes ties including two source electrodes each other, and both ends after arbitrary adjacent two power switchs group establishes ties are all parallelly connected to have electric capacity, the cascade system be by the both ends after four power switchs groups of group establish ties among the next stage basic element circuit parallelly connected to the last one-level basic element circuit in the both ends of arbitrary electric capacity. The utility model discloses a cascade system has realized the voltage output of the different gears of 12n transformation ratio, can be applied to in the design of other fixed gear speed governing, and only use electric capacity as energy storage device, and having reduced the volume of converter, equivalent internal resistance is little and along with the increase of basic element circuit progression does not basically change, power density is high.
