  • Patent number: 12132408
    Abstract: Power converters including electronic-embedded transformers for current sharing and load-independent voltage gain are described. In one example, a power converter system includes an input, an output, a power converter between the input and output, and a controller. The converter includes a first bridge, a second bridge, and an electronic-embedded transformer (EET) between the first and second bridge. The EET includes a capacitor and a capacitance coupling switch bridge. The controller generates switching control signals for the first and second bridges and phasing drive control signals for the capacitance coupling switch bridge in the EET. The controller applies a phase shift to the phasing drive control signals for the EET as compared to the switching control signals for the first and second bridges, so that the voltage across the capacitor in the EET cancels the leakage inductance of the transformer windings in the EET, at any switching frequency.
