Three-Level Phase Shifted soft transition PWM DCDC power converter with high frequency link for arc welders and its extended version

This paper presents some experimental results and practical evaluations of neutral point clamping and flying capacitor hybrid three-level phase shifted soft switching PWM DC-DC high power converter with high frequency transformer and center-tapped rectifier. This new DC-DC converter developed for TIG, MIG and MAG arc welders is implemented by modifying the… CONTINUE READING
