Abstract

Discrete state space modeling of the LCC-type parallel resonant power converter is presented. Using these large signal equations, small signal modeling of the power converter is obtained. State variable feedback control has been integrated with the linear small signal state space model and the associated control aspects are studied. The small signal equivalent circuit model has also been obtained. The small signal state space model has been used to study the small signal behavior of the power converter for open loop and closed loop operation for parameters like control to output transfer function, audio-susceptibility and output impedance. Theoretical results have been experimentally verified
