Abstract
We are considering the problem of controlling AC/DC switched power converters of the Boost type. The control objectives are twofold: (i) regulating the output voltage to a desired reference value, (ii) assuring a unitary power factor by enforcing the voltage and the current delivred by the electric network to be in phase. The considered problem is dealt with by designing a nonlinear backstepping controller involving a cascade-structure. Using tools from the averaging theory, it is shown that the control objectives are achieved.
