Abstract
Power electronic system with pulse width modulation (PWM) control is studied. Behaviour characteristic
for a nonlinear dynamical system is observed and theoretically explained. A DC-DC buck converter controlled by
a voltage feedback is taken as an example. The studied system is described by a system of piecewise-smooth nonautonomous differential equations. The research are focused on chaotic oscillations analysis and analytical search for bifurcations dependent on parameter. The most frequent route to chaos by the period doubling is observed in the
second order DC-DC buck converter. Other bifurcations as a complex behaviour in power electronic system evidence
are also described. In order to verify theoretical study the experimental DC-DC buck converter was build. The results
obtained from three sources were presented and compared. A very good agreement between theory and experiment was observed.
