High-Frequency Power Converters

Catalog description

The High-Frequency Power Converters course covers the analysis, modeling, design, and control of high-frequency (HF) power rectifiers, resonant inverters, and DC-DC converters. Specific topics are (1) overview of advantages and challenges in designing and operating HF converters, including conduction and switching loss modeling, hard- and soft-switching concepts, and switches selection; (2) modeling, analysis, and design of Class D and E voltage- and current-driven rectifiers, inverters and matching networks; (3) HF converters consisting of a cascaded connection of resonant inverters and rectifiers; (4) LLC converter analysis and design; (5) HF converters modeling and control using the Extended Describing Function modeling method, demonstrated on the example of a phase- and frequency-controlled LLC and Series Resonant Converters (SRC), and (6) topology and operation principles of HF Dual-Active-Bridge DC-DC converters. The course includes laboratory exercises where students design, assemble, and test an SRC and program its controller.
