Abstract :
A novel single-stage two-switch three-phase rectifier for up-down AC-DC conversion without input voltage sensor is presented. Although it employs two single-phase SEPIC converters, the proposed converter provides the necessary control over the three-phase line current with near-unity power factor and the phase interaction problem is avoidable.
