A modified series resonant converter with clamped tank capacitor voltage exhibits complex dynamic characteristics due to the clamping diodes. This thesis aims to understand the dynamic behavior of the converter in a three-dimensional state-space. Geometric features of the state trajectories are analyzed and sampled-data models are developed. Based on the small-signal model around nominal operation, a feedback controller is designed. Nonlinear control rules are established to deal with large deviations from the nominal. The study is supported by simulation results obtained using a specially constructed simulator.
