Abstract :
This work concerns the fast steady-state determination of power electronic circuits. Switching converters operate in different modes. In each of these modes a converter is described as a linear time-invariant system (LTI). The steady state Is found with computer simulations performed with Newton-based methods for accelerated steady-state determination. Two methods are investigated: exact and approximated Jacobians. The implementation of zero-crossing detection improved convergence.
