ATTRACTOR OF SERIES RESONANT DC/DC CONVERTER

The state trajectory from starting to the stationary state is simulated and in stationary state analytically calculated. Natural state variables for this circuit are inductor current and capacitor voltage. It was shown that the normalized trajectories in stationary state form one closed loop, so called attractor, composed of four different circular segments. After verifying simulation model, the influence of the quality factor of the resonant circuit on the duration of starting process is examined. By introducing small perturbations in the stationary state, the inherent stability of power circuit is demonstrated. The analysis results can be used for control circuit design.
