Abstract :
In this paper a new large-signal discrete time model for dc-dc converters is derived. The model is meant to overcome the lack of large-signal dc-dc converter models which, firstly, are able to accurately predict converter behavior in different operating modes and, secondly, can be implemented both in Matlab/SIMULINK and HDL language. The model is well suited to perform system level simulation of digitally controlled SMPS using synthesis tools targeted to FPGA and ASIC implementation and, therefore, avoiding time consuming mixed-signal simulations from the first stages of the design.
