Abstract :
The paper describes numerical simulations and experimental evidences of chaotic behaviour in a
simple PWM converter with digital control. Experimental examples of strange behaviour in power
electronics converters are proposed to highlight the non-linear dynamic resulting from switching
operation. Circuit examples are selected to point out the effect of parasitic effects of power electronic
devices and non-linearities in the control. Chaotic transition of PWM converter results as waterfall
period doubling bifurcations determined by increasing the control gain.
The laboratory measurement system is developed using PC, DAQ-board and LabVIEW software so
to obtain an improved usability of the hardware. Moreover, due to the simple set-up, the topic has
been included in a course for graduated student so to improve understanding of chaotic behaviour in
non-linear dynamic electric systems.
