Abstract
A new control technique is proposed to reduce the distortion of UPS output voltage. The Load of UPS is rectifier which has many harmonics on its output current in many cases. The distortion of output voltage by the harmonics is repeated at the same position in one cycle. Therefore we can assume that the next cycle wave form would be similar to the previous one. The repeated error can be estimated and be compensated by the Multi controller at every sampling times.
