Abstract :
A modified series resonant converter with clamped tank capacitor voltage exhibits complex dynamic characteristics due to the clamping diodes. This paper describes work aimed at understanding the dynamic behavior of the converter in a three-dimensional state-space. Geometric features of the state trajectories are analysed, 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 developed simulator
