Abstract: Chaos is a non-linear phenomenon found in all non-linear systems. The dc-dc converters exhibit wide range of bifurcation and chaotic behaviour under certain operating conditions. The weak periodic perturbation (WPP) method is introduced to control the chaos in positive output Luo converter. In this paper, WPP is applied to stabilize an unstable orbit of a chaotically operating current controlled positive output Luo converter and to operate in stable region. The simulations using MATLAB/ SIMULINK shows that the operating region is extended by weak periodic perturbation method.
