Consideration of the Simulation on the Digital Controlled Switching Mode Power Supply System
Shen Zhong-keng · Telecom Power Technologies · 2005
Digital control is the developing trend of the switching mode power supply system,and the problem of how to simulate the digital controlled switching mode power supply system must be resolved in the theoretical analysis. Setting the research on the galvanization power as example,this paper puts forward a method of the digital PI controller by using the Matlab and Simulink.That is to output the pulse phase shift signal with S-Funcion.Thus to realize the simulation on the phase shift full bridge galvanization power system.The simulation results are quite similar to the practice results,which means it should be a close guidance to the development of the digital controlled galvanization power system and can be used for the reference for common digital controlled switching mode power supply.
