  "textContent": "Three-phase single-stage AC-DC converters achieve power factor correction with low phase voltage switch stress. Direct input current sensing is performed to calculate the average input current of the AC-DC converter and implement power factor correction. Embodiments feature high power factor, single stage power conversion, and soft-switching of all switches, resulting in high conversion efficiency in a cost-effective single-stage three-phase structure. The converters have low output voltage ripple without a double line frequency component, which allows non-electrolytic capacitor implementation. The converters are particularly useful in high-power applications such as electric vehicle charging.",
