Soft-Switching Techniques for Three-Phase AC/DC Converters
This invention provides a modulation for three-phase AC/DC converter. This modulation can achieve soft switching and thus improve converter efficiency, especially for high-density-driven high frequency operation. In spite of variable switching frequency operation, this modulation has narrow switching frequency variation range, which reduces switchi...
