The paper deals with an emerging problem of AC to DC power converters: the establishment of the mean value of the rectified voltage. This is a difficult task due to the nonlinear behavior of the capacitor filter, attached to the rectifiers. Are proposed novel, simplified mathematical models both of the controlled and uncontrolled rectifier, useful in analysis and design stage. A software product is conceived to compute the mean value of the smoothed output voltage of the controlled rectifier. The obtained results are validated both by simulation and by comparison with experimental results, highlighting the advantages of the proposed methods.
