Abstract
This chapter studies a capacitor voltage clamped series resonant converter, regulated at constant frequency by pulse-width modulation (PWM-CVC-SRC). The principle of operation, topological states and relevant waveforms are described, after the presentation of the converter power stage diagram. Theoretical analysis is carried out, using the state-plane trajectory approach, which gives the static gain and output characteristics. In the subsequent sections, simplified design example and methodology are provided, along with simulation results. Proposed exercises with answers are included at the end of the chapter.
