Resumen:
The first period-doubling bifurcation of a dc-dc buck converter controlled by a zero-average dynamic strategy is studied in detail. Due to the saturation of the duty cycle, this bifurcation is followed by a border-collision bifurcation, which is the main mechanism to introduce instability and chaos in the circuit.The multiparameter analysis presented here leads to a very complete knowledge of the relation between these two bifurcations. The results are obtained by using a frequency-domain approach for the study of period-two oscillations in maps.First period-doubling bifurcation of a dc-dc buck converter controlled by a zero-average dynamic strategy is studied in detail.
