Abstract

 This  paper  addresses  the  application  of  a  new  Pulse-Wide  Modulation  (PWM)  technique  called  inverted-sine  PWM (ISPWM). This technique can be used to control Voltage Source   Converters   (VSC)   of   custom   power   devices.   The   proposed switching technique uses a sinusoidal reference signal and an inverted-sine as a carrier signal. The ISPWM technique generates  lower  voltage  Total  Harmonic  Distortion  (THD)  in  comparison   with   conventional   Sinusoidal   PWM   (SPWM)   technique.  The  proposed  switching  technique  has  been  studied  on   a   simple   VSC,   Distribution   Static   Compensator   (D-STATCOM) and Dynamic Voltage Restorer (DVR). Simulation results  with  PSCAD/EMTDC  show  the  effectiveness  of  the  proposed switching technique.
