This paper presents the design, characterization, and modeling of a power electronic converter based around Silicon Carbide (SiC) MOSFETs. A practical characterization procedure is proposed which takes a circuit-level approach, as opposed to a device-level approach, using only the power electronic circuit and no additional test circuitry. The converter circuit is general enough that it can represent...
The availability of improved magnetic materials and higher voltage rating semiconductor devices have made the design of high power medium frequency transformers feasible. The paper presents a simple design procedure to determine the core dimensions based on the area product method. A winding design procedure to use foil conductors in the high voltage side to achieve ac-to-dc resistance ratio close...
High frequency transformers are widely used in Switched-mode power supplies and now are being proposed to be used with power electronic converters to replace line-frequency transformers. This paper presents a winding design procedure for minimizing the power losses using foils and solid round wires under sinusoidal excitation to limit the temperature rise. This paper derives the range from which the...
