Three-phase current-fed soft switching PWM converter with switched capacitor type resonance DC link

In this paper, a newly-proposed three-phase current-fed zero current soft switching PWM converter using a new switched capacitor type resonant DC link (RDCL) circuit is described, which is basically operated by the new conceptual optimum PWM pattern for efficient high-power utilization. The working principle, design approach and operating performances of this converter suitable for large capacity applications in industry are discussed. The effectiveness of this soft-switching optimum PWM converter with sinewave current shaping and unity power factor correction schemes is proved on the basis of experimental results.
