Abstract :
Although most current-programmed converters are designed for steady-state continuous mode operation, transient and fault analysis require dual-mode (continuous/discontinuous) models. The popularity of SPICE (Simulation Program with Integrated Circuits Emphasis) has created a demand for nonlinear state space averaged SPICE converter models because execution times of brute-force SPICE models are impractical. The theory, evolution, and use of a fast, nonlinear, duo-mode SPICE model of a current-programmed buck converter is described. A slow brute-force SPICE simulation confirmed results obtained from the fast mode
