Abstract :
The aim of this paper is to show how digital control laws for high-frequency DC/DC converters can be modeled for its application in a simple DSC evaluation board. Therefore, we have developed a specific test-bench for digital DC/DC converters permitting us an easy comparison among different control laws for Voltage Regulator converters. Each law is firstly simulated by means of Matlab/Simulink models and after implemented in our test-bench.
