Abstract
Power converters including electronic-embedded transformers for current sharing and load-independent voltage gain are described. An example 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 between the first and second bridge. The electronic-embedded transformer includes a bidirectional coupling switch bridge. The controller generates drive control signals for quasi-trapezoidal current modulation control of the bidirectional coupling switch bridge. The controller is configured to generate the drive control signals based on a commutation coefficient k and a switching frequency for the power converter. The commutation coefficient k can be set based on an inductance in the electronic-embedded transformer, a capacitance in the bidirectional coupling switch bridge, and a margin for resonant current commutation.
