| Abstract | The authors present the state-of-the-art pulse density modulation (PDM)-type three-phase AC/DC power converter with an active voltage clamped resonant DC link (ACRDCL) network and its digital signal processor (DSP) based digital control strategy to achieve a unity power factor correction and sinewave line current shaping. The new operating principle of the zero-voltage soft-switched three-phase AC/DC converter with a ACRDCL and its instantaneous space voltage vector-based clamping-voltage distributed PDM (modified-PDM) strategy to improve its controllability and operating characteristics are described. Performance evaluations of this modified-PDM converter are discussed using simulation results as compared with the conventional PDM converter. Experimental results for this switch mode rectifier are shown |
