  • Publication number: 20210297000
    Abstract: 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. When the ratio of the DC output voltage to the DC input direct voltage is greater than the transformation ratio, a phase shift between the primary alternating voltage and a series resonance circuit current corresponding to the primary alternating voltage is controlled to zero by changing a clocking frequency clocking the AC voltages. Conversely, when the ratio of the DC output voltage to the DC input voltage is less than the transformation ratio, the phase shift between the secondary AC voltage and a series resonance circuit current corresponding to the secondary AC voltage is controlled to zero by changing a clocking frequency.

  • Publication number: 20200274452
    Abstract: A resonant DC-DC converter includes an inverter circuit, a rectifier circuit and a transformer unit. The inverter circuit is connected to a first terminal of the transformer unit, and the rectifier circuit is connected to a second terminal of the transformer unit. The first and second terminals are galvanically isolated from one another by a first transformer. The transformer unit is configured to adapt a transformation ratio of the transformer unit. The transformer unit has an energy transmission path which includes an inverter and a second transformer, with an input of the energy transmission path being arranged parallel to a primary side of the first transformer and an output of the energy transmission path being arranged in series with the secondary side of the first transformer.
