This work deals with the mathematical modeling of the Source ? of Impedance. initially is presenting what an impedance source is by using examples and applications, indicating where the ? Source stands out among the other sources and also explaining its form of operation. In the modeling, the average state space technique is used, applied to the Source ? and two main highlights are obtained: The simple transfer function and compact due to the use of the magnetizing current of the coupled inductor as a variable of state, and the analysis of the effects of the resistor in series with the capacitor in relation to the voltage capacitor average. For the validation of the mathematical model, the methods simulation and experimental data collection. The following are performed in the simulation: tests: frequency sweep, load step in open loop and loop system closed circuit and sweep through the duty cycle value to ascertain series resistor effects with the capacitor. For the collection of experimental data, a prototype was designed and about tests were carried out: load steps with the controlled prototype and a sweep of the duty cycle with additional resistor in series with the capacitor. In both processes of validation the theoretical data are corroborated
