AB  - This study proposes a new approach of unified power quality 
  conditioner which is made up of a matrix converter without energy storage devices 
  to mitigate the current harmonics, voltage sags and swell. By connecting the 
  matrix converter output terminals to the load side through series transformer 
  and the input side of matrix converter is connected to the supply side with 
  step up transformer. So, a matrix converter injects the compensation voltage 
  on the load-side, so it is possible to mitigate the voltage sag/swell problems, 
  resulting in an efficient solution for mitigating voltage and current related 
  power quality problems. Thus, the proposed topology can mitigate the voltage 
  fluctuations and current harmonics without energy storage elements and the total 
  harmonic distortion produced by the system also very low. It also reduced volume 
  and cost, reduced capacitor power losses, together with higher reliability. 
  The Space-Vector Modulation (SVM) is used to control the matrix converter. Matlab/Simulink 
  based simulation results are presented to validate the approach.
