In this work we focus our study on the transition from hadron to deconfined quark matter, and we shall assume the phase transition is a first-order with two independent components, which are related to the local conservation of baryon number and the global conservation of electric charge. In this study, two different relativistic effective theories are employed to describe respectively the hadron and quark phases, a model with derivative couplings and an extension of the MIT bag model. We then carry out an analysis of the model parameters and the different hyperon-coupling schemes adopted in order to identify their possible influence on the phase transition.
