AC-DC converters are commonly used for providing dc link voltage, adjustable speed drives, UPS application.PWM AC-DC voltage source converter is preferred because of its ability to deliver nearly sinusoidal current at unity power factor. The main objective by controlling of PWM AC-DC converters is to achvied unity power factor and minimum harmonic distortion in input line current. A single phase AC-DC converter is fabricated which will provided desired boosted up DC Voltage with minimum ripple, unity power factor at supply. Here SPWM technique is to used.
