Abstract
This chapter presents and describes the operation of the Series Resonant Converter (SRC). After the presentation of the power converter topology, the qualitative analysis is presented, which includes the description of operation, topological states for each time interval and relevant waveforms. Closed-form solutions for the output characteristics are derived, using the state-plane trajectory analysis technique. Simplified analysis utilizing the first harmonic approximation technique is also included. Both continuous and discontinuous conduction mode are discussed and analyzed. Also included are numerical examples to illustrate the theoretical analysis, proposed exercises with solutions and numerical simulations.
