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 (EET) between the first and second bridge. The EET includes a capacitor and a capacitance coupling switch bridge. The controller generates phasing drive control signals for trapezoidal current modulation control of the capacitance coupling switch bridge of the EET. The controller is configured to generate the phasing drive control signals based on a phase shift coefficient, k, to set a duty cycle of a voltage from the capacitance coupling switch bridge. The controller is also configured to vary k from between 0 to 0.5 based on a load applied to the power converter system or other operating aspects of the power converter.
