Patent number: 11824458Abstract: A DC-to-DC converter converts a DC input voltage to a DC output voltage by generating a primary AC voltage and transforming the primary AC voltage into a secondary AC voltage with a transformation ratio. The DC-to-DC converter has series resonance circuit for each AC voltage phase.
