Abstract :
The theoretically optimal duty-cycle modulation for the lowest possible input current distortion of a single-switch three-phase power factor corrector is analyzed. A simple control strategy which achieves results which are very close to the theoretical optimum is presented. Furthermore problems that arise when an isolation transformer is introduced are explored and a solution is proposed
