The paper presents evidence of the existence of stick-slip oscillations, usually found in mechanical systems with friction, in a class of resonant power converters. It is shown that these converters can exhibit periodic solutions characterized by segments of sliding motion (associated to theoretically infinitely many switchings). Also, numerical and analytical evidence of the occurrence of sliding bifurcations is given. These phenomena have recently been presented in the literature and the paper reports their occurrence in power electronics for the first time.

Abstract
The paper presents evidence of the existence of stick-slip oscillations, usually found in mechanical systems with friction, in a class of resonant power converters. It is shown that these converters can exhibit periodic solutions characterized by segments of sliding motion (associated to theoretically infinitely many switchings). Also, numerical and analytical evidence of the occurrence of sliding bifurcations is given. These phenomena have recently been presented in the literature and the paper reports their occurrence in power electronics for the first time.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
