Bifurcations in a Generalization of the ZAD Technique: Application to a DC-DC Buck Power Converter

Abstract EN

A variation of ZAD technique is proposed, which is to extend the range of zero averaging of the switching surface (in the classic ZAD it is taken in a sampling period), to a number K of sampling periods.

This has led to a technique that has been named K-ZAD.

Assuming a specific value for K=2, we have studied the 2-ZAD technique.

The latter has presented better results in terms of stability, regarding the original ZAD technique.

These results can be demonstrated in different state space graphs and bifurcation diagrams, which have been calculated based on the analysis done about the behavior of this new strategy.
