About MathCAD Modeling of Power Transfer in Buck-Boost AC PWM Converter

This paper is focused on predicting the power transfer in buck PWM AC regulators. The circuit simulation and results prediction were carried out using specific computational tools such MathCAD. The commutation process is studied and the article presents a method to establish the mathematically model of the power transfer. With this model it is possible to determine the load power without the classical steps. Comparative evaluation with experimentally determination is presented.
