Abstract: This paper deals with stability analysis and limit cycle behaviors in DC–DC boost converters with a proportional integral (PI) voltage compensator, which is a popular design solution for increasing output voltage in power electronics. The circuit principle is explained with the help of state space averaging. The transfer function of the system is found by the small signal ac modeling of boost converter. The stability of the converter is found by Routh Stability Criterion. The limit cycle behavior is given by the stability analysis.
Keywords: Stability, Limit cycle behavior, Boost converter.
