Abstract :
The instabilities of the boost converter system caused by large variations of system parameters are explored using multiple-parameter, bifurcation-theory-oriented approaches. It is revealed that, depending on the eigenvalues of the Jacobian of the system, both static bifurcation (jump phenomenon) and dynamic bifurcation (onset of limit cycles) can occur at critical points. The stability conditions for both precritical and postcritical behavior of the system have been obtained and verified experimentally
