Abstract

This paper proposes a new approach for teaching the basic DC-DC converters, aiming a better understanding of these converters by the student uninitiated in the subject. The proposed strategy is to begin by presenting the basic PWM commutation cell and make a generalization of its characteristics, showing that the buck, boost and buck-boost converters have many similarities. This procedure reduces the number of equations and waveforms to be studied. An interesting effect, only present in the boost converter, is the double region of continuous conduction mode (DRCCM). Simulation results show that the mathematical procedure is consistent and easy for designs.
