Abstract: © 2013 IEEE. A large-signal averaged model is obtained to analyze the startup response of a boost converter loaded with a constant power load (CPL) and a peak current mode control (CMC). An analytical methodology is developed for the stability analysis during both startup and steady state. The proposed model corresponds to two operating modes: 1) a reduced-order saturated model during startup mode and 2) an unsaturated full-order model taking place when the system reaches the vicinity of the steady state. The duration of the startup period is also determined using the same model. To verify the validity of the derived large-signal model and the theoretical results derived from it, numerical simulation results from this model are compared with those obtained from a detailed switched model and experimental measurements demonstrating that the model can faithfully predict both the large-signal dynamic response during startup as well as the steady-state regime of the system.
