ELK 519E - Resonant Power Converters

Course Objectives

1. Obtain mathematical formulations required for steady-state and dynamic analysis of DC/DC converters based on resonant operation principle,
2. Derivation of characteristics of series and parallel resonant converters,
3. Soft switching (zero-current or zero-voltage) techniques and application of these techniques to classic pulse-width-modulated DC/DC converters,
4. Calculation of controller design criteria using using large and small-signal equivalent circuit modeling of a frequency-controlled resonant power supplies are also within the scope of this course.
