Abstract
In this paper, the dynamics of a dc-ac resonant self-oscillating LC series inverter is analyzed
from the point of view of piecewise smooth dynamical systems. Our system is defined by two
symmetric configurations and its bifurcation analysis can be given in a one dimensional param-
eter space, thus finding a non smooth transition between two strongly different dynamics. The
oscillating regime, which is the one useful for applications and involves a repetitive switching
action between those configurations, is given whenever their open loop equilibrium is a fo-
cus. Otherwise, the only attractors are equilibrium points of node type whose stable manifolds
preclude the appearance of oscillations.
