Abstract
A high-performance PWM technique in current-controlled AC to DC converter is introduced. This converter used information about source voltage vectors to make good PWM switching pattern that it can control the DC output voltage with reduced ripple factor and rapid response. In addition to reduction of harmonic current, AC input power factor can be controlled to leading or lagging by current reference. Simulation was made based on analytical approach and it showed a good agreement with theory.
