Abstract

This paper presents the theoretical analysis concerning the operating stages of the three-phase dc/dc converter associated with the hybridge rectifier, in order to obtain its dynamic model. The nonlinear instant model in state space form is obtained by the definition of a switching function q(t). From this model, an average nonlinear model is proposed, as well as a linearized model. The dynamic model, the controller design, and also experimental results obtained from a prototype of 6kW are presented.
