Generalized computer-aided discrete time domain modeling and analysis of DC-DC converters

A generalized discrete time domain modeling and andlysis technique is presented for all types of switching regulaors using any type of duty-cycle controller, and operat1nq 1n both continuous and discontinuous inductor current. State space techniques are employed to derive an equivalent nonlinear discrete time model that describes the converter exactly. The system is linearized about its equilibrium state to obtain a linear discrete time model for small signal performance evaluations, such as stability, audiosusceptibility and transient response. The analysis makes extensive use of the digital computer as an analytical tool. It is universal, exact and easy to use.
