**6. Conclusions and future work**

In this chapter, we have presented a generalized procedure to compute Floquet exponents for any number of delays (*τ*) in the control law of PWM switched converters. We have investigated the incidence of *delays* in a digital-PWM controller based on two novel techniques: *Zero Average Dynamics* (ZAD) and *Fixed-Point Inducting Control* (FPIC). Principles of *Floquet theory* and *smooth bifurcation theory* were used to define stability regions. The incidence of control parameters in transient response of PWM switched converters will be analyzed in a future work using a similar Floquet-based procedure.
